| 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. |
