Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
Many large heaps of coal mine waste in the form of shale and coal discards are present in the mining areas of the Eastern Transvaal and Northern Natal. Much of this material has been subject to spontaneous combustion which appears to have overcome some of the deleterious engineering properties associated with the natural Karoo aged sediments.
coarse copper and iron ores. Throughput rates have varied widely, from 272 kgs/hr to 6000 t/h. These systems have been especially successful in coal handling applications from the mine to preparation to transfer and export. Sandwich Belt high angle conveyors also found use in the disposal of refuse from coal preparation plants.

Separately, they are referred to as coarse and fine coal refuse. Coarse refuse is transported to a disposal facility by truck or belt line. Fine refuse typically exits the separation process in slurry form and is disposed of in abandoned mine workings, dewatered and mixed with coarse coal refuse for disposal in fills, or pumped through
The rejects from the two stage Baum Jig are dewatered on a refuse screen and sent to a refuse bin container for loadout by truck. The underflow from the coarse refuse screens is combined with other fine coal refuse products of the plant and sent to the fine coal slurry sump.
The prep plant produces approximately 585 tph of coarse and fine refuse. The coarse refuse consists of refuse screen oversized material, and is transferred by refuse belts to a coarse refuse loadout. This coarse refuse stream consists of all plus 1mm refuse material, and accounts for about 500 tph (% of the plant feed).
