摘要
某含砷铅锌多金属矿石中,金、银矿物种类多,粒度微细(大多数<0.005mm),呈包裹状态赋存于黄铁矿和石英颗粒中,矿石砷含量高达6.12%。研究了中性矿浆浮选银铅、碳酸钠弱碱性矿浆浮选金银矿物,金银粗精矿氰化浸出,取得了较好的技术指标。
In arsenic-lead-zinc polymetallic ore,gold and silver mineral species was complex, particle is fine （majority d0. 005 mm） ,and packed in pyrite and quartz. The arsenic content is 6.12%. Based on the ore characteristics, neutral pulp was used to recovery silver and lead minerals, sodium carbonate pulp was adopted to flotation gold and silver minerals. The gold-silver crude concentrate was leached with cyanide. Good technical index was obtained.
