Mineral Beneficiation and Processing of Coal

2021-5-11  Abstract. Coal plays a vital role in steel production and electricity generation. In recent times, coal production has been increased multiple times as the demand for steel and energy increased. Presently, about 41% of the world’s electricity requirements are met by thermal coals.

Analysis and significance of mineral matter in coal

2002-5-1  Mineral particles can occur in coals at all rank levels, and, in the absence of other inorganics, are usually the dominant form of mineral matter in higher-rank coal deposits. Evaluation of the total proportion of mineral matter may be based on direct analysis methods such as low-temperature oxygen-plasma ashing, or on indirect methods, such as calculation from ash percentage and other chemical
