How does PGM Flotation Work?
The second component which plays a key role when one must conduct PGM flotation either in a concentrator plant or in the laboratory, is the operations component where one must consider the mineralogy of the ore, feed rate, pulp density and particle size to successfully perform the flotation process.

Fig. 2 shows that as pH increased from 9.0 to 10.5 and then to 11.5, the pyrite recovery obtained from the flotation of the ore with 5 % pyrite decreased steadily from 94.5 to 40.6 % and then to 10.3 %. Hence, a direct link between the decreased pyrite recovery in Fig. 2 and the increased Cu grade in Fig. 1 when pH increased could be drawn. The …

Dense Media Separation (DMS) Plants
The upper limit of the ore particle size is related to the ore size, embedding characteristics, and equipment size. In usually, the ore is 50-150mm, and the coal is 300-500mm. DMS can greatly reduce the surrounding rock and waste rock under the same processing capacity, reduce ore grinding consumption, thus reduce production costs.
