Mineral Processing | SpringerLink
An essential characteristic of mineral processing separations is that they are never perfect: some of the valuable product is always in the waste stream, and some of the waste is always in the valuable stream. This is due to the combined effects of mineral inseparability and inefficiencies in the separation process.

Researching Preconcentration with Mineral Processing Equipment
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.
