Development course of MCC Huludao Nonferrous Metals Group Co., Ltd.

Huludao Zinc Factory, the predecessor of MCC Huludao Nonferrous Metals Group Co., Ltd., was founded in Huludao Smelter of Manzhouli Lead Mine Co., Ltd. on 1937. After more than 70 years, the development process is as follows: (1937-1955).

1939 In April, Huludao Smelter imported the patented technology of vertical zinc smelting from Ye Feng Company, New Jersey, USA, and began to build 8 distillation furnaces and 3 gas generators, with an annual output of distilled zinc 10000 tons. 1942 The distillation furnace was completed and put into operation in August, and stopped production in June 5438+February of the following year due to the rupture of the tank, with a total of 84 tons of zinc steamed. 1946 1 month, after the Kuomintang government received it, it only produced sulfuric acid 1347 tons in two years.

After liberation, people in the zinc factory began to resume the production of vertical zinc smelting in the abandoned factory building of 1950. On September 3rd, zinc was smelted in a small experimental furnace, and the first zinc ingot was produced for New China. 1October 9, 65438, 1# and 2# distillation furnaces began to smelt zinc, and 79 tons of zinc was smelted in three months, which marked the success of zinc smelting in vertical tanks for the first time in China. 1 July 1954, all eight distillation furnaces were repaired, and the zinc production capacity reached110,000 tons. At this point, people in the zinc factory have completely mastered the vertical pot zinc smelting technology, which greatly increased the ambition of Chinese people, thus establishing the position of vertical pot zinc smelting technology in the field of non-ferrous metals in China. (1956- 1985 production capacity from 1 10,000 tons to 60,000 tons)

With the needs of national economic construction and development, Huludao Zinc Plant has expanded its production scale since the First Five-Year Plan. During the Sixth Five-Year Plan period, the zinc system has undergone two large-scale system expansions and seven local transformations, and the annual zinc production capacity has increased from 6.5438+0 million tons to 60,000 tons. In the past 30 years, the ability of independent innovation has been significantly improved. 1956, the plate chain zinc casting machine was successfully developed, and the transportation mechanization of zinc castings was realized. In September of the same year, the trial production of silicon carbide refractories was completed, ending the history that China could not produce silicon carbide materials. 1957 The high-temperature oxidation roasting process was successfully tested, and the first high-temperature oxidation boiling roasting furnace in China was built, and the roasting capacity was improved by four times. 1958, the comprehensive utilization workshop was formally established, which pioneered the distillation and extraction of refined cadmium, reached the international advanced level, and successfully produced comprehensive utilization products such as cadmium, indium, lead, mercury and zinc sulfate. 1964 successfully developed a series of products such as high-purity zinc to fill the domestic gap. 197 1 year, 1# distillation column was successfully changed from single tray to double tray, and the daily output was increased from 15 ton to 30 ton, which opened up a new way of refined zinc production in the world. In the past 30 years, the zinc factory has also successfully developed a series of new products, such as advanced zinc oxide, ultrafine zinc powder, zinc alloy, battery zinc cake, zinc wire and hot dip galvanizing, and the quality has reached the international advanced level. At the same time, a large number of zinc smelting talents have been trained and transported for the country, and the vertical pot zinc smelting technology has been improved and improved, laying a solid material and technical foundation for the rapid development of enterprises. (1986- 199 1 year production capacity from 60,000 tons to 200,000 tons)

During the Seventh Five-Year Plan period, the country is in the transition from a planned economy to a market economy, and there are surplus mineral resources and insufficient smelting capacity in the market. Huludao Zinc Factory firmly grasped this favorable opportunity, ran quickly in small steps, and expanded its scale at a rate of 20,000 tons per year by using mature vertical pot zinc smelting technology. The renovation project was put into operation that year, and it was effective that year. The enterprise benefit is increasing at the rate of150,000 yuan per year, and the "Shanghai Zinc" brand zinc ingots are well-known in the domestic and foreign markets. By 199 1 year, the production capacity of zinc plant has reached 200,000 tons, and the profit has reached 654.38+0.2 billion yuan from 40 million yuan, ranking first in the same industry in China in scale and benefit, and becoming a banner of non-ferrous industry. (1992-1999 The production capacity is from 200,000 tons to 430,000 tons)

1992 the nonferrous metal market entered the direct channel, and the zinc factory accelerated the pace of becoming the largest zinc producer in Asia, and began the massive "three factories and one reform" project. In four years, 6.5438+0.3 million tons of electrolytic zinc plant, 60,000 tons of crude copper plant and 6.5438+0.4 million tons of electrolytic copper plant were built and transformed, and the thermal power plant with an annual output of 6.5438+0.4 million kWh was built. 1995 China Nonferrous Metals Industry Corporation merged two old enterprises, Shenyang Smelter and Shenyang Nonferrous Metals Processing Factory, which had suffered losses for many years, into Huludao Zinc Plant and established Huludao Northeast Nonferrous Metals Group Company. In June, 1997, zinc industry was listed on Shenzhen Stock Exchange. (From 2000 to 2009, the production capacity was from 430,000 tons to 520,000 tons)

1999 In the second half of the year, Huludao Northeast Nonferrous Metals Group was placed under the leadership of the newly established copper, lead and zinc group company. In 2000, the state adjusted its industrial policy, China Copper-Lead-Zinc Group was dissolved, and Huludao Zinc Factory was decentralized to Liaoning Province. In May of the same year, Huludao Zinc Factory signed a 450 million yuan debt-to-equity swap agreement with four asset management companies: China Huarong, China Cinda, China Great Wall and China Dongfang. In 2002, the zinc factory and four asset management companies established Huludao Nonferrous Metals Group Co., Ltd. In June 2003, the electrolytic zinc system of130,000 tons was partially reformed and its production capacity was restored to 70,000 tons. In September of the same year, the 90,000-ton lead-zinc closed blast furnace project started construction and was completed and put into operation in 2007. From June 5438 to February 2007, Huludao Nonferrous Metals Group was merged and reorganized by MCC. During this decade, the non-ferrous metal market experienced a process from trough to peak, from peak to trough, and then slowly rose.
