coal rank and analysis in mineral processing

Conducting release analysis by lab scale froth flotation machine is an established method. As regards particle size range for a particular coal sample you can carry out the release analysis test for a size range of 250 microns to 5 microns like that and find out the optimum recovery or grade of the product.

Mineral contentCoal contains a variety of minerals in varying proportions that, when the coal is burned, are transformed into ash. The amount and nature of the ash and its behaviour at high temperatures affect the design and type of ash-handling system employed in coal-utilization plants. At high temperatures, coal ash becomes sticky (i.e., sinters) and eventually forms molten slag.

Relative density or specific gravity of the coal depends on the rank of the coal and degree of mineral impurity. Knowledge of the density of each coal play is necessary to determine the properties of composites and blends. The density of the coal seam is necessary for …

They are a medium-rank coal. Bituminous coals generally have calorific values above 11,500 Btu/lb and volatile matter below 14% (ASTM, Jackson, 1997). In the Illinois Basin (and western Kentucky), however, the lower rank end of what are termed bituminous coals in the United States have calorific values of 11,100 to 11,300 Btu/lb.

In the past coal maceral separation have been carried out based on density difference e. g., sink-float analysis, density gradient centrifugation (DGC) techniques etc. These approaches are of limited success. Froth flotation is a physico-chemical process separating particles on the basis of difference in surface properties in a vessel consisting of two distinct zones viz., pulp and froth zones.

Coal is the leading product of the Indian mining industry, accounting for 78 percent of total mineral sector production. India has an estimated coal reserve of 301.5 billion tons (10 percent of global reserves). India's demand for coal continues to increase to meet the needs of coal-based thermal power plants and the steel industry.
