Abstract

The paper describes the results of experiments on the washing of some lower seam of Jharia in a 6” diameter cyclone and a 2,000 g.m. sub-aeration type Denver cell. The need for a survey of the cleaning possibilities of the difficult coals of Jharia and Bokaro is stressed. Industrial processes that can be tried are listed. The problems of screening and drying of coals, treatment of slurry, effluent etc., recovery and utilization of the middlings and rejects are considered in some detail. The authors then draw attention to the importance of evolving an integrated plan for the washing of difficult coals in India.
