Recovery of platinum from flotation tailings using physical and metallurgical processing

本试验的目的是对磁性污泥废渣、PGM和铜/钼浮选尾矿进行选矿，将PGM和Cu/Mo升级到浮选过程中进一步回收或升级到精炼厂。结果表明：采用磁选法可将PGM浮选尾矿中的Pt精矿精矿精矿浓缩约50~60次，浮选尾矿中的Cu精矿精矿精矿精矿精矿可浓缩30~60次，Mo精矿精矿精矿精矿精矿精矿精矿精矿精矿可浓缩约30~60次。物理分离和化学/湿法冶金技术将这些废物中丢失的贵重金属浓缩和回收到可接受的等级，供随后使用，并作为各自工业的额外资源。

The objectives were to beneficiate the magnetic sludge waste, PGM and Cu/Mo flotation tailings, in this work was to upgrade PGM and Cu-Mo to return to flotation process for further recovery or upgrading to the refinery. The results indicate that main conditions and processes of separations could be concentrated to Pt approximately 50~60 times from PGM flotation tailings by magnetic separation, 30~60 times to Cu and Mo from tailings by flotation, respectively. The physical separation and chemical / hydrometallurgical technology to concentrate and recover valuable metals lost in these waste to acceptable grades for subsequent are used and concluded as additional resource in respective industries.
