Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG ) or ferrosilicon (SG ), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink. T he SG of separation is the SG of the media slurry, and can range from (for coal

washing—normally using jig and dense medium for coarse coal, and flotation for fine coal. Transport of coal from mines or preparation plants to consumers is also very important for the coal cost and environment. The main methods of inland transporting of coal are rail, road, barge or other water transport, slurry pipeline and conveyor. Ocean transportation is carried out by barges or ships

Densemedium beneficiation of fine coal was also used in other countries, of which the plants at Homer City in the USA and Curragh in Australia were the best known. The first application of densemedium cleaning of fine coal was, however, at the Tertre plant in Belgium1. This plant was built in 1957. About nine years later, a second fine coal densemedium plant was built at the Winterslag
