CHINA MOLYBDENUM CO., LTD. Tungsten Company
CHINA MOLYBDENUM CO., LTD. Tungsten Company, a wholly-owned subsidiary of CMOC, was started in September 2015. As a comprehensive application demonstration engineering of low grade scheelite, the project is Luanchuan sub-engineering of comprehensive application demonstration base for molybdenum, tungsten and iron resources, which is jointly approved by former Ministry of Land and Resources and Ministry of Finance. The project takes low-grade complex scheelite from CMOC molybdenum tailings as raw material and adopts new environmental protection process of comprehensive tungsten smelting recycling of "soda pressure leaching-alkali extraction-evaporation for coarse molybdenum-tungsten separation, ion exchange for deep tungsten-molybdenum separation and evaporation and crystallization" (jointly researched and developed with Central South University for 5 years) to recycle and get ammonium paratungstate, ammonium molybdate and phosphorus ore powder comprehensively. The new process and technology are awarded by China Nonferrous Metals Industry Association as reaching "international leading level" and "the First Prize of China Industry-University-Research Cooperative and Innovative Achievement". With 2 invention patents, it is awarded with the first prize (one) of Hunan Science and Technology Progress Award. Its approved budget is 126.9084 million yuan and design scale is annual output of 10,000t ammonium paratungstate and 1,000t ammonium molybdate.
The project scale is implemented in three stages:
With 109.8 million yuan of investment, Phase I (September 2015) constructed production lines with annual output of 5,000t ammonium paratungstate and 500t ammonium molybdate. The project completed construction and started production in March 2016.
With 43.7 million yuan of expansion investment, Phase II (March to August 2018) constructed 2000 t/year APT and 200 t/year ammonium molybdate.
With 9.7 million yuan of total project investment, Phase III (January 2019) expanded production lines of 1,000t ammonium paratungstate and 100t ammonium molybdate; construction, commissioning and production are completed in March 2020.
Currently, APT production capacity is up to annual output of 8,000t APT and 800t ammonium molybdate production capacity. Total industrial output value completed 696 million yuan from January to August 2020 and was expected to break 1 billion yuan all year round; from March 2016 till now, about 26,000t APT and 3.7 billion yuan of industrial output can be completed in total, realizing about 300 million yuan of profit.
Tungsten Company operates under laws and attaches importance to safety, environmental protection and other compliance constructions: complete 48 million yuan of safety and environmental protection facility investment successively; complete dual safety prevention and acceptance work, ultra-low boiler emission reform, comprehensive water treatment and recycling project, waste gas treatment project (organic waste gas and hydrogen sulfide) and new approval project (fume hazardous substance removal).
Under concern and guidance of governments at all levels, CMOC Tungsten Company forges ahead, seizes opportunity, conducts fine management, optimizes and explores constantly, and improves and optimizes the team in development constantly. It has production and technical teams consisting of 246 employees, about 60 postgraduates, undergraduates, junior college graduates and other discipline technicians as well as hired doctors, professors and experts. The company is selected by Central South University as the rare metal practice base.
With the Fourteenth Five-Year Plan just around the corner, CHINA MOLYBDENUM CO., LTD. will meet new opportunity and challenge, focus on talents, rely on science and technology, continue strengthening enterprise management, attach importance to safety, promote production and protect environment as always to make more new contribution to leap-forward development of CMOC undertaking and national construction!
