| Abstract: |
| All sulphide mineral flotation is adopted in Jinchuan to produce nickel-copper mixed concentrate. Owing to the characteristic change of the ore and its importance to flotation, process mineralogy research is in urgent necessary. Mineral compositions, dissemination characteristics and particle size distributions of the target minerals and the liberations of the grinding products of the ore in Jinchuan No. 2 mine area are systematically investigated by modern physics and chemistry analytical methods, which make clear the mineralogy factors affecting the flotation. Points out the approaches to improve the flotation index, provides base for further reducing the content of MgO in the concentrate and increasing the recoveries of nickel and copper . |
