Coal cleaning does add additional cost to the coal price however there are several benefits to reducing the ash content which includes lower sulfur content less ash to be disposed lower transportation costs since more carbon and less ash is transported since coal cleaning is usually done at the mine and not the power plant and increases boilers are realized but reimbursement of extra cost of beneficiation for washed non coking coal needs to be considered Key Words Coking Coal Middlings Rejects Deshaling Coal Washing Steel Plant Power Houses I INTRODUCTION There are a number of washeries under construction now and these are expected to be completed by
