【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.更多还原
