On January 8, at the 2018 National Science and Technology Awards Conference held in Beijing, Hunan Shizhuyuan Nonferrous Metals Co., Ltd. (hereinafter referred to as "Shizhuyuan Company") assembled the "Tungsten Fluorine Phosphorus Calcium-Containing Strategic Mineral Resources Flotation Interface" The "Technology and Application" project won the second prize of National Science and Technology Progress Award. This is after the company won the second prize of the National Science and Technology Progress Award in 2001, "The new technology of comprehensive beneficiation of the tungsten, molybdenum and bismuth complex polymetallic ore-the persimmon garden method", and then won the national award.
Shizhuyuan Company's tungsten-molybdenum-bismuth polymetallic deposit is known as the World Nonferrous Metals Museum because of its large ore reserves and many types of minerals. The polymetallic mineral resources are rich in mineral resources, but the ore grade is low, the mineral particle size is fine, and the beneficiation recovery rate is low. The low efficiency of resource utilization restricts its efficient recycling. The efficient recovery technology of tungsten, molybdenum and bismuth is not only the main scientific research direction of Shizhuyuan Company, but also a national scientific and technological research topic. Enterprises or joint research and development with related universities or independently organize internal research. The award-winning new technology of comprehensive beneficiation of tungsten, molybdenum and bismuth complex polymetallic ore-Shizhuyuan method has not only improved the recovery rate of tungsten beneficiation by more than 5 percentage points, but also achieved good results in the same type of mining enterprises.
Aiming at the worldwide problem of flotation separation of calcium-bearing minerals such as tungsten ore, phosphate ore and fluorite, "Fluorine Interface Assembly Technology and Application of Tungsten Fluorine Phosphorus-bearing Strategic Mineral Resources" takes interface chemistry as the core and passes the system foundation Research, develop new methods of selective collector assembly, develop beneficiation technology and beneficiation wastewater utilization technology that match the characteristics of resources, form a new theory and new technology system for the efficient utilization of strategic resources of tungsten, fluorine, and phosphorus calcium, and solve complex tungsten mines The problems of low utilization rate of colloidal phosphate rock and high-calcium fluorite resources and difficult reuse of waste water have obtained good resource utilization and economic benefits, which has effectively promoted the technological progress of the industry.
On the same day, He Binquan, the general manager of Shizhuyuan Company, participated in the National Science and Technology Award Conference on behalf of the company and received the award certificate.
