Coal mining Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment ...
The coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling 20 billion to 25 billion and net income between 1 billion and 2 ...

Coal is a combustible rock mainly composed of carbon along with variable quantities of other elements, mostly hydrogen, sulphur, oxygen and nitrogen. Coal occurs as layers, called coal beds or coal seams, that are found between other sedimentary rocks. Coal is slightly denser than water but less dense than most of the rocks of the Earth's crust ...
Abstract. Coal flotation of fine material has both economical and environmental benefits by recovering as much coal as possible from runofmine coal and by reducing air and water pollution due to the elimination of sulfur from clean coal and reduction in the solid amount which goes into the stream or in recirculating plant water.

Improving the Properties of Mined Coal. Kentucky coal is improved by the partial removal of the impurities—sulfur and ash. The cleaning process to remove impurities from the coal is often called beneficiation, coal preparation, or coal washing.. In general, coal cleaning is accomplished by separating and removing inorganic impurities from organic coal particles.
The process flow diagram in Fig. 2 illustrates a two module DMS plant. The runofmine (ROM) coal ore is collected in a silo and fed to two different DMC modules through automatic feeders which ...
