Calculation of probable coal enrichment indices

Abstract
Parameters determining the results of gravity concentration of finely crushed coals. Disclosure of minerals, yields and compositions of fractions, quality of the obtained concentrate depend on the degree of crushing. The finer the coal is crushed, the greater the disclosure of minerals during crushing, the greater the amount of pyrite and mineral impurities (or rich in their aggregates) are extracted from the coal, the better the quality of coal obtained by gravity concentration of the crushed mass.
