Recently, the General Office of the Ministry of Natural Resources issued the "Catalog of Advanced and Applicable Technologies for Mineral Resource Conservation and Comprehensive Utilization (2025 Edition)," which includes a total of 376 technologies. "Key Technology and Equipment for High-Quality Recovery of Refractory Copper-Sulfur Ores" by BGRIMM Machinery & Automation Technology Co., Ltd. was selected.

The Key Technology and Equipment for High-Quality Recovery of Refractory Copper-Sulfur Ores addresses the challenges posed by high sulfur content and natural activation in the original ore, which leads to similar surface properties of copper and sulfur, making them difficult to separate, as well as low recovery rates and grades for both metals. Through significant innovations and breakthroughs in flotation equipment, reagents, and process flows, developed from three levels—fundamental theory research, core technology, and engineering transformation—this key technology and equipment for the high-quality recovery of refractory copper-sulfur ores was created. This technology provides a relatively mature technical solution for the efficient development of refractory copper-sulfur ores. It can be used alone or in combination to promote the efficient development of similar types of mineral resources. It has been widely applied in the recovery of refractory copper-sulfur ores at multiple mines, yielding considerable economic and social benefits. At the same time, it can promote the technological advancement of supporting flotation equipment for sulfide ores in non-ferrous metal mines.
