Abstract
Publisher Summary This chapter discusses the phase composition of coal mining and preparation wastes and its role in determining the trends of their usage. Coal wastes are a valuable mineral raw. In practical examination to determine the trends of coal wastes processing, conventional analysis are used––chemical and petrographic. It is difficult to make forecasts concerning coal waste utilization on the basis of the results of chemical analysis, as its data do not reflect the fact of the occurrence of one same oxide as useful, neutral, or undesirable for processing. The application of X-ray analysis allows to completely solve the problem stated and to determine a set of minerals existing in coal wastes, their ratios, and absolute quantity. The quantitative data obtained help to determine the phase composition of coal wastes for coal wastes of individual enterprises as well as the nature of mineral distribution for basins, ranges of their occurrence, and prevailing minerals.
