China magnesium industry has a bright future.

China's magnesium industry is an advantageous industry that can participate in global competition.

Yes:

1, the unit investment is low.

2, the production cost is low. Because other stages of ore, coal and magnesium smelting

The price of raw materials is low, and the labor and management costs are not high, so generally speaking,

The production cost is low.

3. Magnesium and related resources are abundant. China is the country with the richest magnesium resources.

One. The total reserves of magnesite and dolomite in Qinghai Province are 2.7 billion t and 4 billion t respectively.

Potassium magnesium salt and coastal magnesium halide have great reserves. Secondly, I

China's coal resources, power resources and labor force all have the advantages of participating in global competition.

Potential.

In the new century, China's magnesium industry will change from a global producer and trader.

Easy-to-big country is striding forward to the global magnesium industry power. Production capacity of electrolytic magnesium in China in 2005

From the existing 1.9 million t (0. Minhe magnesium factory. Fushun aluminum plant has a capacity of 7 million t,

Zunyi Titanium Factory (5,000 tons) increased to 69,000 tons. ..

Challenges and opportunities faced by magnesium industry in China

1 has developed rapidly and attracted worldwide attention.

Since the mid-1990s, the magnesium industry in China has entered a high level.

During the period of rapid development, the production capacity and output continued to increase. Production capacity from

0 130000t soared from 1987 to the current 280000t, an increase of 93%.

Times; The output increased from 1988 to 01290,000 t in 2000.

More than10.9 million t, an increase of more than 65 times. Magnesium output in China in 2000

It accounts for about 88% of magnesium production in western countries and has become the first in the world.

Magnesium country. After a tortuous road and difficult exploration,

China's magnesium industry has finally attracted the attention of the world, as shown in figure 1.

Figure 1 1 988 ~ 2000 magnesium output in China

2 total control, forced by the situation

Due to the lack of basic research on magnesium in China, the production of magnesium

There is also a lack of communication between enterprises and magnesium users, which makes magnesium develop in China.

The application is seriously lagging behind. With the rapid growth of magnesium production in recent years,

Domestic magnesium consumption is growing slowly, with an annual consumption of only about 20,000 t.

There is a serious surplus of magnesium production, and about 87% of magnesium produced in China is exported.

At present, China imports magnesium from an importer (199 1).

0 1.52 million t), and became the world's largest exporter of magnesium metal.

On a global scale, based on a good forecast of the magnesium market prospect,

In recent years, many countries are planning to build and expand magnesium plants. At present, there are abroad.

Twenty-three magnesium projects are under construction or about to be built, including eight in Australian universities.

Leah. Most of these new projects are planned to be implemented from 2000 to 2005.

Put into production in. According to analysis, the total market demand of western countries in 2005

The volume will reach about 4610.8 million t, but the global total production capacity will be estimated at that time.

Reached143120,000 t, far exceeding the market demand. Due to the continuous adoption

With advanced equipment and technology, it is expected that the product cost will be greatly reduced. if

If more than 20 projects are completed as scheduled, it will definitely affect the magnesium industry in China.

Form a big impact, as shown in table 1.

In order to avoid excessive competition, waste of resources and investment, national economy and trade

The Committee has listed new magnesium smelting as a prohibited investment project. State Economic and Trade Commission

It is stipulated in the Catalogue of Nonferrous Metals Projects Prohibited from Investment at Present that in the future.

No new magnesium smelting is allowed within three years, and a batch of magnesium is forced to be shut down and eliminated.

Backward production technology, poor product quality, waste of resources and serious pollution,

Small and medium-sized enterprises that are inefficient and fail to meet the requirements of safe production. therewith

At the same time, the Ministry of Land and Resources and the State Economic and Trade Commission have also included magnesium smelting.

List of prohibited land supply projects.

3 adjust the stock and enhance the stamina.

3. 1 structural adjustment, just in time

Metal magnesium is called a new engineering material of 2 1 century, and its research

Governments and enterprises all over the world attach great importance to research and development. acting on international convention

Economic Integration and China's Entry into WTO and National Economic Strategy

With the structural adjustment and the implementation of the strategy of developing the western region, China's magnesium industry is in the midst of.

While facing severe challenges, it also ushered in major development opportunities. I

The development and application prospect of magnesium industry in China has attracted the attention of government departments.

The Ministry of Science and Technology attaches great importance to the development and application of magnesium materials.

New technology development plan. In addition, the ratio of magnesium to aluminum in China is the highest in the world.

In low countries, the ratio of domestic magnesium price to aluminum price is about 0 185, which is much lower.

It is at the level of 1 165 ~ 2 in western countries. All in all, this is the tone now.

Improve the industrial structure of magnesium industry in China and accelerate the development and application of magnesium in China.

The best time.

3.2 Some views on stock adjustment

Under the premise of implementing total control, the stock should be adjusted reasonably.

Overall, it is beneficial to improve the overall competitiveness of China magnesium industry and magnesium industry.

Long-term development. Drawing lessons from the development experience of foreign magnesium industry and combining with me

Combined with the specific situation of China, the suggestion of implementing stock adjustment in China magnesium industry comes from

Start from the following aspects.

3.2. 1 Establish a large magnesium company and reshape the new image of magnesium industry.

Due to the large number of domestic magnesium plants (the number of magnesium plants is about 7.

Times), the production scale is small (the average production scale of foreign magnesium plants is about that of China.

27 times), there are more enterprises engaged in magnesium export (more than 200),

Therefore, the state cannot effectively manage and coordinate the magnesium industry. part

The product quality of magnesium factory is also unstable, coupled with long-term export, the price is unexpectedly thrown out.

Buying and selling, in international trade, has serious short-term behavior, which is disturbing.

International magnesium market, the overall image of China magnesium industry in the world

Have a bad influence. From 1994, China exported pure magnesium (including

Magnesium content >; 97% unwrought magnesium) has been successively influenced by the United States, the European Union and India.

Countries such as anti-dumping sanctions have suffered huge economic losses. Representative

For example, unwrought rolled magnesium contains magnesium E 99 18%, 1999 and

Compare the annual average price 1998, including Russia and Ukraine.

The price of magnesium in Rotterdam warehouse, including China, remained basically stable, but in China,

The export price of magnesium has been falling sharply since 2000 in China.

The decrease of magnesium remains constant, as shown in Figure 2.

Figure 2 The gap between the export price of magnesium in China and the world price of magnesium.

The distribution of magnesium production capacity in China is relatively concentrated, only in Shanxi, Henan and Ningxia.

The magnesium production in these three areas accounts for 85% of the national magnesium production.

Yes, it is very conducive to the establishment of large magnesium companies. We should vigorously advocate the existence of …

Enterprises with competitive advantages expand their production scale through mergers and leases,

Achieve economies of scale through low-cost expansion and accelerate magnesium production in China.

Enterprises are developing towards collectivization and scale. Effectively eliminate bulls.

The strange phenomenon of low-price sales reshaped the international development of magnesium industry in China.

New image.

3.2.2 Revitalize the stock, stabilize the quality and improve the investment benefit.

Domestic magnesium plants are less affiliated to state-owned enterprises, mostly local enterprises and

Township enterprises. Not only the production scale is small, but also the technical equipment is relatively backward.

There is a widespread phenomenon of low capacity utilization and idle waste of assets.

199 The average capacity utilization rate of global magnesium plants was 8 1%, while

The average capacity utilization rate of magnesium plants in China is only 72%, which is obviously lower than that of national magnesium plants.

The world average. About 50% of magnesium production capacity in China.

The utilization rate of troops is less than 70%, and some are as low as 50%. China is near 100.

In domestic magnesium factories, there are not many enterprises with stable product quality and recognized by foreign businessmen.

Many, only 10 enterprises introduced vacuum spectrometers, and only three enterprises.

The industry has passed the ISO 9002 quality system certification.

Domestic magnesium plants should constantly improve the level of production equipment and strive to revitalize.

Stock assets, do everything possible to stabilize product quality, and firmly establish and create famous brands.

New marketing concept of products and brand-name products, improve investment efficiency.

Benefit, realize the preservation and appreciation of state-owned assets.

3.2.3 Strengthen cooperation with magnesium users to jointly resist market trends.

dangerous

In order to ensure the supply, sales and price stability of magnesium, foreign magnesium users

There is a trend of asset reorganization and joint investment with magnesium enterprises. Rude

Volkswagen holds 35% of the shares of the Dead Sea Company, and the American Ford Company is in an Australian university.

Hyderabad Investment Company signed a long-term agreement with General Motors. magnesium alloy

Gold manufacturers should take the initiative to get the recognition of die-casting manufacturers before they can fight.

Open the market, such as the Dead Sea Magnesium Factory, because its magnesium alloy has been developed.

Lesler's certification has greatly improved the production capacity of magnesium alloys in a short time.

Expand. Referring to the development experience of foreign countries, it is suggested to introduce foreign countries through internal introduction.

Type, in line with the principle of mutual benefit, to take the form of cooperation and joint venture, signed a long-term

Supply and marketing agreements and other forms, and establish secrets with large magnesium users at home and abroad.

Contact to enhance the development potential of enterprises and jointly resist market risks.

3.2.4. Strengthen new product development and optimize product structure.

Western countries are the main consumption areas of magnesium, and magnesium consumption in 2000.

It accounts for about 95% of global magnesium consumption. Magnesium production capacity in western countries

There is a serious shortage of electricity, and 40% of magnesium consumption needs to be imported from China and CIS.

Mouth. Desulfurization of aluminum alloy, magnesium die casting and steel is the main source of magnesium in western countries.

Want to waste the field. The fastest growing area of magnesium consumption is die casting.

In the past five years, magnesium die castings have grown at an average annual rate of more than 25%.

Long predicted that by 2004, the die casting industry will become the largest user of magnesium.

Among the magnesium products exported from China, the main products are forged magnesium and magnesium scraps.

Magnesium powder particles account for the vast majority, and magnesium alloys with high added value (others)

Export ratio of unwrought magnesium and magnesium fabrication products (wrought magnesium, etc.). ) yes

Lower it.

About 37% of China's magnesium products are exported to EU countries.

Domestically, with the EU exporting magnesium to China (magnesium content >; 97% unwrought

Magnesium) on the basis of the original tariff rate of 3 1 17%, double or flat.

With higher tariffs, China's magnesium exports are facing a more severe situation, while China's.

The situation of magnesium industry is even more difficult.

China's magnesium industry wants to get rid of the current predicament and set up large-scale magnesium.

On the basis of industry companies, focus on attracting funds and outstanding talents.

Just came up. Large magnesium companies should not only be able to produce magnesium products, but also

Have the ability to develop new technologies and new products, integrating production, scientific research and application.

As a use. According to the production and application status of magnesium in China, magnesium will be widely used in the future.

In the process of technological transformation and new product development, magnesium enterprises must

Do not pay attention to domestic and foreign market research, pay attention to qualified scientific research.

Study all long-term cooperation. As there are a large number of small and medium-sized magnesium plants in China.

Some did not entrust a qualified design institute for formal design, because

But in production, it is generally in original mining, indigenous smelting and simple addition.

In the construction stage, the quality of products can not be guaranteed, resources are wasted and the environment is polluted.

The environment hopes to attract the attention of relevant state departments, and in the future.

In the technical transformation of magnesium plant, the recurrence of such incidents was effectively prevented.

4 conclusion

Due to the lack of reasonable planning and scientific demonstration, the magnesium industry in China has developed.

The development speed is too fast, the industrial technology level is not high, and the development and application of magnesium in China

It's far behind. The implementation of total control and stock adjustment is not only

At present, the main problem to be solved in China magnesium industry is also magnesium in China.

The fixed development policy of future industry.

Problems and future development direction of magnesium industry in China

Since 1990s, the magnesium industry in China has developed rapidly.

The output of magnesium jumped from the ninth place in the world in the early 1980s.

Ranked second only to the United States. Non-ferrous metals in China

It has become the fifth largest metal in the industry after aluminum, copper, lead and zinc.

Nowadays, magnesium industry has become one of the pillar industries in China to earn foreign exchange through export.

One.

1 overview of magnesium industry in China

China is a country rich in magnesium resources.

According to statistics, the proven reserves of magnesite in China reach 27.

Billion t, ranking first in the world. Dolomite reserves exceed 7 billion.

T, distributed in most parts of China. Magnesium resources in salt lakes are also different.

It is often very rich, and the reserves of magnesium chloride in Qarhan Salt Lake in Qinghai are very high.

Gundam 1, 61.500 million t. There are many kinds of magnesium resources in China, with high grade and strong suitability.

Meet the needs of various smelting methods.

China produces magnesium by electrolysis and Pidgeon process.

Technology. Electrolytic magnesium smelting has been produced in China for 40 years.

Historically, Fushun Aluminum Plant and Minhe Magnesium Plant are all produced in this way at present.

Wait a minute. In 1990s, Fushun Aluminum Factory introduced 105kA from the former Soviet Union.

Technical transformation of plate electrolysis technology, DC per ton of crude magnesium

The consumption is reduced by more than 2000kWh, as shown in table 1 [1].

For example, it consists of MA2 1 alloy (Mg 4 %Al 0 15 %Mn.

112% zn01001%be) has the following properties.

Quality: tensile strength (σ b) = 285 ~ 305 MPa, yield strength.

(σ 012) =133 ~138 MPa, elongation (δ) = 6 10 ~

6 15 %〔6〕。

Russia's Solikamsk magnesium factory developed this kind.

The manufacturing technology of acicular granular magnesium was introduced and put into production in 1994.

This needle-like granular magnesium production line. The method is to use electricity in the air.

Liquid magnesium is made into granular magnesium by magnetohydrodynamic principle.

3 Conclusion

(1) Accelerate the deep processing of magnesium to meet the social demand for magnesium powder and granules.

Demand of granular magnesium (magnesium granules) and traditional milling technology of magnesium powder

Methods comparison, crude magnesium is directly melted and refined for spraying and feeding.

It is more promising for magnesium smelters to produce magnesium powder by ball milling.

And practical.

⑵ The demand of domestic and foreign iron and steel enterprises for granular magnesium is better than that at home.

Demand for magnesium powder. Therefore, in the porous centrifugal barrel, magnesium is made.

Liquid rapid cooling dispersion granulation will be the first choice for granular magnesium production.

Method, this is also the development road of magnesium factory.

Minhe magnesium factory completed the second phase expansion on 1997, and was formed.

Increased the production capacity of 7000 tons/year. It is estimated that the second phase expansion project will be completed.

After the Ministry is put into production, Minhe Magnesium Plant may reduce the production cost of magnesium.

About 20%, which will open a way for electrolytic magnesium smelting in China.

New way [1]. Pijiang magnesium smelting has a history of more than ten years in China.

Production history of.

According to incomplete statistics, China's metal magnesium production enterprises are

It has reached more than 400 sets, and the production capacity has increased from 1987 to 0130,000 t,

Increased to the current15 ~180,000 t/a. The output is from 1987.

0130,000 t has grown to about 90,000 t in 1997, an increase of nearly 30%.

Time magazine. The output of primary magnesium in China ranks second in the world after the United States.

A little. The annual magnesium consumption in China is estimated to be 1 15 ~ 20000 t.

70% ~ 80% of magnesium needs to be exported. 199 1 year export

Yes, 18t, 1997, increasing rapidly to 7 180000t, 1998, 1.

From June to June, the export volume of magnesium has reached 41.4000 t, ranking first in the world.

First place, accounting for 25% of the world magnesium trade [2].

2 China magnesium industry problems and measures to be taken

Take countermeasures

According to statistics, in the world magnesium production capacity, electrolytic magnesium smelting accounts for.

80 %。 However, 90% of magnesium metal produced in China is made of leather.

Made by Jiang Fa. Electrolytic production of magnesium is suitable for large-scale construction.

Magnesium factory, the product cost of magnesium is low, and the product quality is easy to control.

Pidgeon process is used to produce magnesium metal, although the production scale is compared.

Flexible, the product quality is slightly better than that of electrolytic magnesium,

However, this method belongs to batch production, with low labor productivity and high quality requirements.

The reduction tank is made of nickel-chromium steel, and the product cost is high. At present, foreign scale

The largest magnesium plant has a capacity of 665,438+500,000 t/ a, which is not available in China at present.

A magnesium factory with an annual output of more than 10,000 tons. According to incomplete statistics,

Magnesium plants with an annual output of over 3,000 t in China only account for the national magnesium output.

It can be about one third [3].

Fushun Aluminum Factory, Minhe Magnesium Factory, Hunan and other key enterprises in China.

Magnesium factory, etc. , the product quality is stable, and it has been recognized as inspection-free in Japan.

Yes Several years' practice has proved that China's magnesium products have entered the international market.

There is a certain degree of competitiveness on the court. But because some small magnesium factories

The unstable quality of our products has affected our export reputation. 1995

Since then, the quality problems of magnesium ingots exported from China have occurred one after another in the international market.

Problems, coupled with domestic exporters selling at lower prices, make China.

The price of magnesium in the international market is extremely low. Taking magnesium ingot as raw material

For example, the average FOB per ton of 1995 is $3,444, and the average FOB per ton of 1997 is $3,444.

In 2000, it dropped to $2,254. In just two years, China's metallic magnesium

The export volume doubled, but the export price fell 1/ 3.

Since May 1998, the export price per ton of magnesium has further dropped to

1900 ~ 2000 USD [2]. The export volume of magnesium metal in China is

Sharp decline, such as1998 July, China undeformed magnesium (magnesium content

≥99 18%) was only 4805t, and it was 1997 in the same period.

It is 25% lower than 1998 in June and May, respectively.

10% and1215% are reduced [4].

China's magnesium industry is suffering from capital shortage and power shortage.

Due to the restriction of high electricity price and other factors, electrolytic magnesium smelting has not been carried out.

Can get better development. The largest electrolytic magnesium plant in China-

Magnesium has not been put into production in Minhe Magnesium Factory because of the second phase expansion project.

Electrolytic magnesium electrolysis still uses diaphragm electrolysis, which consumes high power.

The manufacturing cost of magnesium ingots alone is 14000 ~ 15000 yuan/

Tons. The magnesium branch of Fushun Aluminum Plant stopped production because of the high electricity price.

The start-up is seriously insufficient, and the production cost of magnesium ingots is as high as 20,000 yuan/

Tons or so, discontinued in August 1998 [5].

The implementation of anti-dumping makes the production and management of magnesium metal in China

It has been severely hit. At present, there are about 85% magnesium factories in China.

Fall into a closed or interrupted state [2]. It is expected that with the intensification of market competition

In China, more magnesium plants will be forced to close or shut down.

Stop production. But at the same time, foreign countries are stepping up the construction of new magnesium plants.

The pace of establishing and expanding the production capacity of existing magnesium plants has taken a fancy to the lack of

Huge magnesium market. Characteristics of newly-built magnesium plants abroad in recent years

Yes: ① There is an economic scale, and the annual production capacity is generally around 50,000 t..

Yes, it will be built in two phases; (2) Choose the most advanced technology today.

Have a stronger competitive advantage; ③ Construction of main facilities for magnesium production.

At the same time, consider the deep processing of products, or automobile manufacturers.

Families directly invest in shares and share products in order to achieve higher production.

Product added value and more stable market. New foreign manufacturers, such as

Dead Sea Magnesium Factory in Israel, Bekankanger Magnesium Factory in NH Company and

The capacity of newly-built Magnola magnesium is 5 ~ 6 18.

Ten thousand tons/year, the scale advantage is obvious. Especially the latter is cheap.

Using serpentine tailings as raw material, the most energy-saving repolarization is adopted.

(AlcanMPC type) magnesium electrolytic cell, DC consumption per ton of magnesium is

10000 ~12000 kw h, there will be strong competition at low cost.

Force. These new factories are expected to be put into operation around 2000 [1]. Odda

The proposed Queensland magnesium plant in Australia has a design capacity of 90,000 tons/year.

This factory is a joint venture between Queensland Metal Company and Ford Company.

It is planned to be completed in 2002 [4]. China's magnesium industry is still maintained.

If the strategic structure is not adjusted in time, it will be in 2000.

After that, China's magnesium industry may face great difficulties in survival.

Difficult.

The author thinks that if we want to improve our country quickly in a short time.

The overall competitiveness of magnesium industry has effectively strengthened the national industry.

Regulatory capacity, where conditions permit, it is urgently needed to build 1 10,000 tons.

Large-scale electrolytic magnesium plant above grade.

The electricity cost in the products of electrolytic magnesium factory accounts for about the manufacturing cost.

Therefore, about 40% of the cheap electricity used is electrolytic magnesium.

The factory has a strong market competitiveness, so electrolysis method

The magnesium factory should be located in a place with sufficient electricity, low electricity price and close to raw materials.

Place of origin

Magnesium chloride should be the focus of future electrolytic magnesium smelting in China.

(potassium carnallite, brine) resources, and the demand for by-products.

Enterprises that use chlorine as raw materials use advanced and reliable electricity.

It solves the magnesium smelting technology and gives full play to the magnesium resource advantage of salt mud. green

The in-table reserves of potassium chloride in Chaerhan Salt Lake in Hainan Province are114.5 billion.

T, accounting for 97% of the national proven reserves; Magnesium chloride reserves 16 15

Billion t, also ranked first in the country; Lake water in Yuncheng Salt Lake, Shanxi,

After the production of mirabilite, brine rich in magnesium chloride can be produced every year.

About 4 million cubic meters. During the Eighth Five-Year Plan period, Chaerhan, Qinghai Province

Magnesium smelting industry with potassium carnallite as raw material in salt lake

Test, after more than three years of repeated tests, was obtained in Minhe magnesium factory.

Successfully passed the former China Nonferrous Metals Industry Corporation.

Appraisal of weaving technology. Potassium carnallite I in this industrial test

The secondary dehydration technology and device have reached the international level, and the secondary dehydration

Technology and supporting facilities have reached the international advanced level. Recently,

Take the lead in applying the test results to the industrial construction in China.

Industrial Project-3000-ton magnesium expansion project of Qinghai Minhe Magnesium Factory

The project has been completed and partially put into operation.

The salt mud in Golmud, Qinghai Province is not only rich in potassium and magnesium resources.

Rich, and has a unique resource advantage. Golmud

Natural gas reserves are abundant, and the total reserves of Sebei natural gas field are 47.5 billion.

Cubic meters, the recoverable capacity is 28 billion cubic meters, and the annual gas production of the gas field.

It is estimated that 10 billion cubic meters, laying natural resources from Sebei to Golmud.

Gas transmission pipeline 190km, annual gas transmission capacity 1 1 100 million cubic meters.

rice. Qinghai Petroleum Administration Bureau develops economy in Golmud Kunlun.

A natural gas power plant with an installed capacity of 2 1MW will be built in this area.

In order to comprehensively utilize the potassium and magnesium resources of Qarhan Salt Lake in Qinghai Province

Planning of Salt Lake Industry Group Co., Ltd. and Qinghai Petroleum Administration Bureau

Co-build a magnesium metal plant with an annual output of 1 15000 t and 60000 t.

T PVC factory. The magnesium factory plans to adopt the most advanced potassium in the world at present.

Carnallite magnesium smelting process and domestic advanced technology and equipment, magnesium

Electrolysis adopts 120kA non-clapboard magnesium electrolyzer, and the production electricity is supplied by

The proposed 300 MW natural gas power company will supply and smelt magnesium.

Potassium carnallite was prepared by Qinghai Salt Lake Industry Group, the project preparation unit.

Group Co., Ltd. is responsible for the supply of chlorine gas, a by-product in production.

Waste electrolyte from PVC plant (containing KCl ≥72%).

All of them are supplied to Qinghai Salt Paste Industry Group Co., Ltd.

The resource conditions of Ermu City and the current electricity price, after calculation, if the electricity price

When 0 130 yuan/kw h is taken, the unit product per ton of magnesium ingot is

This is about 13700 yuan; Even the electricity price is 0 135 yuan/kw.

H, the unit product cost per ton of magnesium ingot is only 14800 yuan.

About, far below the current magnesium ingot level of magnesium production enterprises in China.

The average production cost is 2 1 15 1 yuan/ton [3]. The reason of product cost

So low, in addition to being close to the origin of raw materials, is a more important reason.

With the support of the joint venture, the problems of by-product chlorine and waste electrolyte were solved.

Sales problem. The author thinks that making full use of salt in Qinghai Province

Lake potassium and magnesium resources and energy advantages, take the road of comprehensive utilization of resources.

Road, the construction of large electrolytic magnesium plant, is the future development of magnesium industry in China.

The only way for industry.

3 Conclusion

Facing the increasingly competitive international magnesium market, in order to

Quickly improve the overall competitiveness of China magnesium industry in a short time.

Force, there is an urgent need to build a batch (at least one) where conditions permit.

A) Large electrolytic magnesium plant with a capacity of over 10,000 tons. think

Joint venture, cooperation and other ways to attract domestic and foreign magnesium users to participate.

And steadily and gradually expand the sales of magnesium products.

Market. At the same time, it advocates market competition and the survival of the fittest.

A large number of small cobbler magnesium factories lack market competitiveness to ensure that

Protect the country's industry regulation ability and change the current disorderly competition into

Orderly competition leads China magnesium industry to be healthy and orderly.

Direction development.
