摘要
采用部分优先浮铜—铜镍混浮—铜镍分离的阶段磨选流程对某地高铜低镍硫化矿石进行了小型试验研究。结果表明 ,在碳酸盐介质中BY - 5是含镁脉石矿物的有效抑制剂 ;YD组合药剂可在低碱介质中实现铜镍分离 。
The experimental study on flotation separation of a sulfide ore containing high sulfur and low nickel was carried out by using the technological flowsheet of selective flotation of copper-bulk flotation of copper and nickel-separation of copper and nickel. The results showed that the BY-5 is an effective depressant of gangue minerals containing magnesium in the carbonate medium. A new-type mixed depressant YD can realize separation of copper and mickel in the weak alkaline medium and obtain satisfactory separating efficiency.
