Coal beneficiation can be done at two stages: 1. Mining stage #178; removal of stones and 2 Also, reduction of ash content in the coal also brings down the burn capacity of the coal, or gross calorific value, to produce more electricity thus reducing yield of the coal.
#0183;#32;It resulted in depletion of better quality of coking coals and now we are left with poor quality coals. As the ash content of the available coking coal reserves in the country is seldom below 17 %, Beneficiation of coals becomes a must. The average ash content in raw coal usually varies from 30 to

Raw coal may be sold as mined or may be processed in a beneficiation/washing plant to remove noncombustible materials (up to 45% reduction in ash content) and inorganic sulfur (up to 25% reduction). Coal beneficiation is based on wet physical processes such as gravity separation and flotation. Beneficiation produces
#0183;#32;A combined ash reduction and desulfurization process for 60 mm fine coal was proposed. The E p was when high sulfur fine coal was cleaned by compound dry cleaning.. The organic sulfur can be effectively removed by microwave desulfurization apparatus.
#0183;#32;Beneficiation transforms coal ash from a byproduct to a product. Changes in burner configurations and other environmental controls have impacted quality, and beneficiation is needed for many sources of ash just to meet the minimum national standards.
BIOBENEFICIATION OF HIGH ASH COALS AN EXPLORATORY ATTEMPT . ABSTRACT: The paper discusses the experimental results, which indicated a reduction of ash content by 15 18 %, the ash reduction being dependent on the type of media used, and
Washed coal continues to have ash content after beneficiation. Conversely, coal constitutes a small but nonetheless significant part of the rejects. This residual coal is a valuable economic resource that should neither be ignored nor discarded. Indian coals typically have ash content in excess of 40 percent.
