The dry magnetic separator is used for sorting dry magnetic minerals, and is mainly used for selecting large-sized, coarse-grained ferromagnetic ores and fine-grained weak magnetic ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m.

Abstract. In the early 1980`s, the commercial need for a single stage centrifugal dense medium separator which would be an alternative to both jig washers and 2-stage dense medium plants, led to a decision being taken to develop a new separator, the main requirements of which would be: To have a capacity no less than current washing plant, to treat a size range …

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.

The cut-off density of separation is always higher than the feed medium density. Medium-to-coal Ratio. To run a DMC smoothly, it is necessary to maintain the volume of the medium and the solids feed rate. The medium to coal values should typically range from 3.5 to 4. Rarely, a DMC can perform well with ratios below 3.
