Heavy Media Separation Process

2016-5-22  Sink and Float separation process One of the first commercial applications of a medium to effect a sink-float separation used a fine silica sand suspension for treating anthracite coal and is known as the “Chance” process. The method used for cleaning the medium is decantation which limits the minimum grain size of the solid in the suspension.

RECENT DEVELOPMENTS IN PRECONCENTRATION

2016-5-22  Dense media separators are commonly used for preconcentration of coal and diamonds but less commonly for other mineral systems such as lead and zinc. Due to lower head grades adding to the complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones.
