摘要
采用分步粗选,粗精矿再磨工艺流程,并配以弱性pH值调整剂和混合捕收剂,对某高砷多金属硫化矿进行分选试验,获得理想效果,各有用金属的回收平均达到90%以上,而各有用金属中的砷含量均降至05%以下。
An experiment upon separation of arsenopyrite from a polymetallic sulphide ore sample bearing high arsenic content has been conducted.Rougher flotations in stages and regrinding of their concentrates were adopted with the use of weak agent for modifying pH value and combination of different collectors.satisfactory metallurgy was attained with recovery of each valuable metal over 90% in its concentrate containing arsenic below 0 5%。
