Western Mining Group Technology Development Co., Ltd., with high-efficiency flotation reagents at its core, developed new-type lead-gold-silver collectors and zinc depressants, establishing an efficient mineral processing technology system. This technology effectively reduced zinc impurity content in lead concentrates and significantly improved the recovery efficiency of precious metals. After the research results were industrially applied at Western Mining Co., Ltd. Xitieshan Branch, mineral processing capacity increased from the designed 1.32 million mt/year to 1.5 million mt/year; lead and zinc recovery rates reached 92.76% and 95.66%, respectively, while gold and silver recovery rates increased by 4.65 and 2.73 percentage points, respectively.
