Jan 01, 2013 In 1981, the Dugda II and West Bokaro washeries in India were possibly the only ones in the world to crush coal to a very small top size ( 13 mm). This was for the purpose of liberating the coal from non-coal, then washing the 13 0.5 mm fraction in DMCs, with the − 0.5 mm fines being treated by flotation ( Table 8.11 )

Beneficiation of an Indian non-coking coal by column

Jun 08, 2016 Jun 08, 2016 Beneficiation of non-coking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel for integrated gasification combined cycle plant (IGCC), the ash content in the coal should preferably be below 15 %. Indian coals are characterized

observed that –3 mm top-size fraction has a relatively better potentiality to produce clean coal compared to any other top-size fractions (–20, –15 and –10 mm). However, the crushing of ROM coal to fine size is more power consuming and will also generate more fines (–0.5 mm). This would require modification in the washing practices
