刚果民主共和国某铜钴矿尾矿选矿试验研究

对刚果民主共和国某铜钴矿尾矿样品进行的选矿试验研究表明，在样品含铜0．90％、含钴0．06％、铜氧化率为95％、钴氧化率为93．33％的情况下，经过擦洗磨矿后，采用硫化钠作为硫化剂，经过三粗三精一扫的混合浮选，产出含铜13．54％、含钴0．52％的氧化铜精矿，铜回收率达72．51％、钴回收率达47．29％，该工艺具有流程及药剂制度简单、易于实施等优点，适宜于处理同类型尾矿资源。

Experimental Study on the Mineral Processing of a Copper and Cobalt Tailings in the Democratic Republic of the Congo

The experimental study on the mineral processing of a copper and cobalt tailings in the the Democratic Re- public of the Congo shows that the sample contains 0. 9% of copper with oxidation rate of 95% and contains 0. 06% of cobalt with oxidation rate of 93.33% ,after scrubbing grinding, adopting three roughing with one scavenging and three cleaning mix flotation mineral processing with sodium sulfide as vulcanizing agent can produce single concen- trate wih copper content of 13.54% and recovery of 72.51% and with cobalt content of 0. 52% and recovery of 47.29% ,the processing has advantages of simple and easy to be implemented with simple flotation reagents.
