蛇纹石对硫化铜镍矿浮选过程影响及其分离研究进展

Effects and Researching Developments of Serpentine on the Flotation Processing of Cu-Ni Sulphide Deposit

浮选精矿降镁作为硫化铜镍矿浮选分离体系中的难题,国内外对此展开了大量研究。本文论述了蛇纹石对硫化铜镍矿浮选的影响机理,并从选矿工艺流程的优化、有效浮选药剂的开发和电化学浮选角度,综述了降低硫化铜镍矿浮选精矿氧化镁含量的有效途径。

It is one of the most difficult questions that the MgO content of the float concentrate is decreased in the flotation seperation of Cu--Ni sulphide deposit. It has been studied for a long time by the researchers all over the world. This paper elucidates the effect mechanisms of serpentine on the flotation of Cu--Ni sulphide deposit and summarizes the effective approaches of the MgO reduction in the proc--Ni sulphide deposit in terms of optimum craft flows , efficient flotation reagents and technologies of flotation electrochemisty.
