新疆某伴生铜钴矿降砷回收工艺研究
|
摘要
对新疆某含砷低品位铜钴矿进行了降砷选矿工艺试验研究,并对伴生钴进行了富集回收探索研究。通过流程及浮选药剂条件试验,确定在-74μm 80%的磨矿细度条件下,采用优先浮选铜、抑制剂抑砷、尾矿回收伴生钴工艺,得到了铜品位24.29%、铜回收率83.16%、As品位低于3‰的铜精矿产品,得到钴品位4.72‰、回收率58.04%的钴硫精矿产品。
Research on reducing arsenic and recovering mineral processing technology of certain arsenicbearing copper ore in Xinjiang was carried out, and the recovery exploration study on asscociated cobalt was also conducted. Based on condition experiments of flow sheet and flotation reagents, the flow sheet of Cuselective flotation with reducing arsenic, recovering asscociated cobalt from tailings was adopted on this condition that grinding fineness is-74 μm 80%. The better results of the copper concentrate grade of 24.29%and copper recovery of 83.16% with the arsenic grade less than 3‰ were obtained. Meanwhile the Co-S concentrate grade of 4.72‰ with recovery of 58.04% was obtained.
