Information

     

The Mineral Processing Division is one of core divisions of Zijin Research Institute of Mining and Metallurgy /Xiamen Zijin Technology of Mining and Metallurgy Ltd., State Key Laboratory of Comprehensive Utilization of Low-Grade Refractory Gold Ores. 
The Division currently has a multi-disciplinary group of scientists and engineers specializing in mineral processing, chemical engineering and organic chemistry, and is well equipped with laboratory platforms for gravity separation, magnetic separation, bench-scale flotation and continuous piloting flotation separation testing.  
MPD is devoted to provide world-class applied research and deliver innovative solutions to address the challenges in mining industry. The Division offers high-efficiency beneficiation technology, novel flotation reagents development, process investigation, plant survey, both laboratory and field services to help our customers achieve positive and sustainable development. Since its establishment, the Division has provided technical services for worldwide mining subsidiaries of Zijin Group Co. and has undertaken more than 200 scientific research projects. 

 

Mineral Processing Division is able to provide crushing and grinding properties test, beneficiation feasibility test, laboratory bench scale test, laboratory continuous test, semi-industrial pilot scale test and full-scope industrial scale test.
