【摘要】 采用新型组合抑制剂CA-PN 以及高效选择性改性组合捕收剂A-214,处理金川二矿区含镁高的低品位镍铜矿.在一段磨矿75% - 0.08m m ,自然pH介质条件下,经一粗二精二扫工艺流程,获得浮选精矿含Ni7.09% ,Cu3.90% ,MgO6.25% ,Ni回收率76.30% ,Cu 回收率78.51% 的闭路试验结果.技术指标达到国内先进水平

【Abstract】 The novel composite depressor CA\|PN and highly effective and selective modified composite collector A\|214 have been applied to treat low grade nickel\|copper ore with high magnesium content in NO.2 Mining Area of Jinchuan. Under the condition of one \|stage grinding to 75% -0\^08mm and natural pH value, after the technological flow of one roughing, two concentratings and two scavengings, the following closed\|circuit test results can be obtained: the flotation concentrate contains Ni 7\^09%, Cu 3\^90% and MgO 6\^25%; the Ni recovery is 76\^30% and Cu recovery 78\^51%. The technical results have attained the advanced domestic level.
