法国Minemet研究所研究从复杂铅锌黄铁矿矿石中回收中金与银的问题,研究了3种处理黄铁矿精矿的方法: 1.古典的煅烧后的氰化法,结果金银的回收率分别为55和60％; 2.热烈解黄铁矿继用氯化铁浸出,贵金属的浸出率为90％,但需大量投资; The Minemet Institute in France studied the recovery of gold and silver from complex lead-zinc-pyrite ores and studied three methods of treating pyrite concentrates: 1. The classical calcination of cyanidation results in gold-silver The recoveries were 55 and 60% respectively; 2. Pyrite pyrite followed by ferric chloride leaching, precious metal leaching rate of 90%, but a large investment;
