由于环境保护的原因,多金属矿石浮选应少用氰化物,然而,尽管已研究出某些矿石的无氰分离方法,Belousov选矿厂处理G1ubo—tchansk多金属矿石却仍在使用氰化物,用量为每吨矿石950克,其中90％用于铜铅精矿分离。这芒‘先是由于这些矿石的组成和所含金属的比例所致。若刁:使用氰化物,就既没有合适 Cyanide should be used less for flotation of polymetallic ores because of environmental concerns. However, cyanide is still being used at the Belousov concentrator for the treatment of G1ubo-tchansk polymetallic ores, although no cyanide separation has been developed for some ores 950 grams per ton of ore, of which 90% for the separation of copper and lead concentrate. This is because of the composition of these ores and the proportion of metal they contain. If Diao: The use of cyanide, it is neither suitable
