The main industries of Lin Kai Group

Lin Kai mining industry is the pillar industry of Lin Kai Group and the foundation of Lin Kai Group's development. Kaiyang Phosphate Mine, the predecessor of Lin Kai Group, is one of the three major phosphate mine production bases in China during the Twelfth Five-Year Plan period, and its construction started on 1958.

Phosphate mining area belongs to the national planning mining area, located in Jinzhong Town, Kaiyang County, Guizhou Province, with a length of15km from north to south and 5km from east to west, covering an area of about 85km2. Phosphate rock resources in phosphate rock mining areas have large reserves, high grade, less harmful impurities and low cadmium content. The average content of P2O5 is 33.67%, of which the phosphate-rich reserves with a content over 32% account for 78% of the total reserves in China. It is the only important raw material base in China to directly produce high-concentration phosphorus compound fertilizer without mineral processing, and it is an ideal wet fertilizer raw material and a high-quality raw material for producing pollution-free green phosphorus chemical products.

After more than half a century's development, since the new century, Lin Kai mining industry has persisted in mining technology innovation and unremittingly promoted the construction of modern mines. Mine production technology and equipment have reached the domestic first-class and world advanced level. The "sublevel open stope mining method with bolt roof protection" and "self-gelling filling mining technology with all wastes from phosphorus chemical industry" won the first prize and the second prize of national scientific and technological progress respectively. The mine production capacity has been greatly improved, reaching 5 million/year. Now it has developed into the largest underground phosphate mining chemical mine in China, which has laid a solid foundation for the sustainable development of phosphate mining and made outstanding contributions to the development of phosphorus chemical industry in China. From 65438 to 0988, Lin Kai Group began to take the road of "combination of mineral and fertilizer", and the phosphorus chemical industry has developed for more than 20 years. Over the past 20 years, relying on the unique advantages of phosphate rock resources, Lin Kai Group has adhered to self-reliance and rolling development, and the phosphorus chemical industry has continued to grow and develop. The annual production of high-concentration phosphorus compound fertilizer is 3.5 million tons (including 2.5 million tons of diammonium phosphate, 800,000 tons of monoammonium phosphate, 200,000 tons of calcium superphosphate and 25,000 tons of sodium fluorosilicate), and the supporting construction of sulfuric acid production equipment is 4 million tons, phosphoric acid production equipment is 6.5438+0.6 million tons, and the production capacity of yellow phosphorus is 33,000 tons.

Phosphorus chemical industry has entered the stage of structural adjustment and industrial upgrading after completing the industrial layout of high-concentration phosphorus compound fertilizer as the basic fertilizer. At present, according to the "new three-step" development strategic plan of Lin Kai Group, the coupling of phosphorus chemical industry, phosphorus chemical industry and building materials, phosphorus chemical industry and chlor-alkali chemical industry, phosphorus chemical industry and petrochemical industry is being realized, and high-tech, multi-product and high-end products such as industrial grade, feed grade and food grade are developed vertically, organic chemical industry and inorganic chemical industry are developed simultaneously, and wet-process phosphoric acid and thermal phosphoric acid are developed simultaneously, so as to realize the high-tech and multi-product phosphorus fine chemical industry. Lin Kai Coal Chemical Industry originated in 200/. Relying on the rich advantages of coal resources in Guizhou and the talents and technical advantages of Jianhua Company in developing coal chemical industry for half a century, after nearly ten years of development, it has formed 600,000 tons/year of synthetic ammonia, 380,000 tons/year of methanol, 80,000 tons/year of nitric acid, 6,543,803,000 tons/year of ammonium nitrate, 6,543,805 tons/year of nitro compound fertilizer and 6,543,800 million tons/year of nitro compound fertilizer.

On the basis of forming the comprehensive synthetic ammonia production capacity of Lin Kai Group's 3.5 million tons/year high-concentration phosphate compound fertilizer production capacity, Lin Kai coal chemical industry has now entered the stage of developing fine chemical industry of coal chemical industry. According to the development concept of circular economy, we will focus on the development of coal gasification technology, and develop and produce high value-added fine coal chemical products such as clean fuel, synthetic plastics and photosensitive materials through carbonyl synthesis of synthesis gas, methanol oxidation or combination, and ammonia oxidation or carbonization. Lin Kai Group's property service industry is the tertiary industry developed in accordance with professional management and market-oriented operation by stripping the enterprise logistics service system in the reform of management system and operation mechanism. Its main business includes property, catering, medical treatment, breeding, planting, bathing, etiquette, industrial tourism and other services.

Through nearly ten years of professional management and operation, relying on the main business, Lin Kai's property service industry has developed by leaps and bounds, accumulated rich management experience in the property service industry, and cultivated a well-trained and enterprising professional team. While providing professional property services for Lin Kai Group, the property service industry actively explores the external service market and accelerates the development of diversified industries. Property services and catering services continue to extend to external high-end markets, and have been extended to Xifeng, Kaiyang, Huishui and Guiyang, laying a solid foundation for further development and growth. The building materials industry of Lin Kai Construction Engineering is mainly divided into two parts: architectural engineering design and construction, real estate development and new building materials. The phosphorus construction industry started from the survey, design, construction and real estate development of a large number of engineering construction projects of the Group, and gradually developed and expanded. It is a real estate developer with Grade A qualification of engineering survey and measurement, Grade A qualification of chemical mine design, Grade B qualification of chemical engineering, Grade B qualification of new building materials engineering design, Grade B qualification of all kinds of engineering consultation, Grade II qualification of general contracting of construction, and Grade II qualification of professional contracting of architectural decoration engineering, with an annual housing development and sales capacity of 654.38+10,000 m..

Lin Kai new building materials industry is a new industry developed by Lin Kai Group in the process of developing circular economy. In order to realize the sustainable development of enterprises and the comprehensive utilization of solid wastes such as tailings and phosphogypsum produced in the production of mines and phosphorus chemicals, Lin Kai Group has developed patented technology with independent intellectual property rights after more than ten years of scientific and technological research, and comprehensively utilized yellow phosphorus tail gas, yellow phosphorus slag and phosphogypsum to produce new phosphogypsum bricks with high strength and water resistance, thus building the world's first phosphogypsum brick with independent intellectual property rights and core technology. A series of new building materials, such as new phosphogypsum brick, building gypsum powder, dry-mixed mortar, foamed gypsum and sintered slag brick, were developed, which provided new building materials for the country to implement the policy of prohibiting the production and use of clay bricks. Relying on the brand influence of Lin Kai and the strong support of 5 million tons/year phosphate rock and 3.5 million tons/year high-concentration phosphate compound fertilizer production base, Lin Kai's trade industry has achieved leap-forward development since the beginning of the new century, from a single phosphate rock trade to a phosphate fertilizer trade, and from a related product trade to an unrelated product trade. At present, the domestic market has established a marketing network covering all major grain and cotton producing areas and most cultivated land, and international trade has spread all over Southeast Asia, South Asia, the Middle East, South Africa, Europe and the United States, gathering a large number of trading partners. The strength of marketing network, brand influence and market share are getting stronger and stronger.
