湖南宝山铜矿是矽卡岩型铜铋铜钨矿床,主要矿石矿物有黄铜矿、辉铜矿、辉钼矿、辉铋矿、黄铁矿等。选厂采用部分混合—优先浮选流程回收铜精矿、钼精矿、硫精矿。原设计的铜钼混合粗选作业中,只采用煤油作捕收剂,铜的回收率低(<50％);原设计的铜钼分离作业中,只采用大量Na_2S作抑制剂,钼精矿的产品长期达不到一级品(含Mo 47％),影响企业经济效益的提高。
Hunan Baoshan Copper Mine is a skarn copper bismuth copper tungsten deposit, the main ore minerals chalcopyrite, chalcocite, molybdenite, bismuthinite, pyrite and so on. Selected plant using a partial mixing - priority flotation recovery of copper concentrate, molybdenum concentrate, sulfur concentrate. In the original copper-molybdenum roughing operation, only kerosene was used as the collector, and the recovery rate of copper was low (<50%). In the original design of copper-molybdenum separation, only a large amount of Na_2S was used as the inhibitor and the molybdenum concentrate Of the products fail to reach the first-class products (containing Mo 47%) for a long time, which will affect the improvement of the economic benefits of the enterprises.
