Dense medium separation of ultra-fine coal
WebDense 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. WebNov 1, 2010 · It should be noted that the particles can be separated by dense-medium cyclones according to their different density. Moreover, comparing to the water-only devices and splitters, the...
