Coal preparation plants usually use a number of processes taking advantage of the difference in density between coal and the mineral matter to separate the two ( dense medium baths, froth flotation, cyclones). Other processes involved in the preparation plant include stockpiling and recovery, dewatering, disposal of waste ( "coal wash") and ...

The first wash plant (a temporary coal handling and preparation plant) was commissioned in the first half of that year. The plant is expected to process the coal at a rate of 100tph. It is equivalent to 600,000tpa of runofmine (ROM) coal. The first export shipment of the thermal coal from the mine was in December 2011.

Coal Washing Exploration in India dates back to 1900s; though, first coking coal washeries in India were installed after independence. At present, most of the coking coal washeries are owned by Public Sector Companies; whereas, most of the noncoking coal washeries are owned by Private Sector. Even after six decades of coal washing practices, there has not been significant development in the ...

Introduction: Coal Washing is a process of enrichment of combustibles in coal by removal of noncombustible impurities utilizing industrial separators mainly based on difference in Specific Gravity of Coal and associated impurities like Shale, Sand Stones etc. so that we get marketable coal suitable for the target consumers. The Washed Coking Coal is meant for Steel Plants.
