What Is Coal Preparation? Energy.gov
网页2013年2月21日 What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.

Processing of coal fines using air fluidization in an air table
网页2016年4月10日 Abstract. Dry beneficiation of fine coal was investigated using air fluidization in a vibrating air table. A systematic study based on a response surface method of experimentation revealed the features of separation. The ash content of the − 1.0 mm coal feed was reduced from 25.8% to 16.2% with 40.9% mass yield of the clean coal.
