TECHNOLOGIES F0R FINE COAL BENEFICIATION IN INDIA

The ash content of the coal fines increased to 25% or even more, which had adverse effects if blended with coarse cleans. The coal fines are normally enriched with virtrinite, which is the important component responsible for increasing the coking propensity of the total cleans. Hence, the coal fines need to be up graded to the acceptable quality.
