ABSTRACT

Coal Beneficiation means the separation of coal particles of low ash from the runof-mine coal by physical and/or physico-chemical treatments. As it comes from the mine, coal is known as Run-of-mine coal (ROM coal) and consists of a range of sizes from chunks to small particles mixed with some dirt and rocks. In most cases, this ROM coal is subjected to various operations principally size reduction and screening, beneficiation (separation), and dewatering (if wet beneficiation operations are used) to meet certain market requirements as to sizes, ash, sulfur, moisture, and heating values. Coal Processing is a term that is used to designate the various operations performed on the ROM coal to prepare it for specific end uses such as feed to a coke oven or a coal-fired boiler or to a coal conversion process without destroying the physical identity of the coal. Coal Processing is recognized as a combination of science, art and engineering, recognized in its own right as a vital link between the production and marketing of coal.
