复杂多金属硫化矿综合回收试验研究

Experimental Research on Comprehensive Recovery of Complex Polymetallic Sulphide Ore

针对云南某以铜、锌、金、银为主的多金属硫化矿进行了最佳药剂试验研究,在低碱性介质下实现了铜锌与硫的浮选分离,对伴生金、银进行了综合回收。低碱介质试验指标比高碱介质条件下铜、锌、金、银的回收率分别提高1.92、2.83、10.93、11.91个百分点。

Experimental research is done on a polymetallie sulphide ore of Yunnan, realize the flotation separation of copper zinc and sulfur under low alkaline medium, comprehensive recover the associated gold and associated silver. Compare the experiment index of high basic medium and low alkali medium, recovery rate of copper,zinc,gold,silver are raised by 1.92,2.83,10.93,11.91 separately.
