摘要
采用柠檬酸作络合剂、六偏磷酸钠为抑制剂,对金川镍矿二矿区矿石进行了提质降镁浮选试验研究,并与现场药剂体系的实验室闭路试验结果进行了对比。试验结果表明,在原矿含镍1.36%、含铜0.86%、含MgO28.19%的情况下,经1粗2精3扫、中矿顺序返回的闭路处理,最终可获得镍品位为9.68%、铜品位为5.04%、MgO含量为6.33%、镍回收率为84.32%、铜回收率为69.13%的铜镍混合精矿,各项指标均优于现场药剂制度下的实验室闭路试验指标。
Using citric acid as complex agent, sodium hexametaphosphate as inhibitor,the flotation tests on quality increase and magnesium decrease for No. 2 Mine Area of Jinchuan Nickel Mine are made and compared with the laboratory closed-circuit tests under on-site reagent system. The tests indicate that for the raw ores containing nickel of 1.36% , copper of 0.86% , MgO of 28.19% , the final nickel-copper mixed concentrate with Ni grade of 9.68% , Cu grade of 5.04% ,MgO content of 6.33% , nickel recovery of 84.32% and copper recovery of 69.13% are obtained by the closed-circuit process of one roughing-two cleanings-three scavengings-middles back to the flow-sheet in turn. Each index in the tests above is better than that in the laboratory closed-circuit tests under the system of on-site pharmacy.
