Based on the ore properties of our client’s newly constructed copper-gold-silver mine, our company has customized and developed HB-421, obtaining an invention patent for “A Composite Collector for Sulfide Ores and Its Preparation Method.” This increases the main metal beneficiation recovery rate from 88% to 95%, increasing the client’s annual profits by over 20 million yuan. In response to environmental protection requirements, we have developed an environmentally friendly copper inhibitor that can replace sodium cyanide, achieving the client’s performance targets. This is the first domestically successful industrial application of a low-toxicity agent to replace sodium cyanide, alleviating the environmental burden on our client.
