ore, but costs nearly as much to run at 90 % capacity as at full load. The foregoing type of calculation might not then apply. In suitable cases, dense-media separation can sort a wide size-range of ore cheaply. The tonnage of suitable feed must be sufficient to justify the cost of installing a plant. Easily movable plants can be rented.

In coal preparation plant, dense medium separation is usually combined with flotation, to process coarse or fine-grained materials. Dense medium separation is usually used for separation of the coarse material with particle size >0.5 mm, while flotation is used for processing of the coal slime with particle size <0.5 mm.

Introduction. A coal dense medium separation (DMS) plant makes use of the principle of density separation to upgrade mined coal and produce metallurgical coal or power station coal. The objective of the DMS plant operation is to produce coal product within a minimum quality specification and maximum possible yield (England et al., 2002).

Simplified flowsheets for the dense media and flotation processing option are presented in Figs. 3, 4, and 5. The crushing facility (shown in Fig. 3) is comprised of 3 stages and can operate independent of the concentrator. The concentrator has three (3) distinct areas: dense media separation, flotation and dewatering.

In most coal cleaning plants, separation frequently starts with gravity separation—a technique that separates particles based on differences in density—because of its operational simplicity, low cost, and high efficiency. For example, jig and static dense medium separation are commonly applied for coarse particles …

Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded end-product, clean coal being separated from the heavier shale or ...
