The huge amount of ash generated in our power plants can serve as important source for extraction of important ash constituents. Kusmunda area in Korba Coal field is an important source for power coals and therefore a bulk coal sample from the area has been studied in details as a test case for distribution of mineral matter in coal ash in different possible constituted dispatch material to power plants taking silica as a major and marker ash constituent. While, silica as percent of ash from samples under study remains within close limits, its retention in coarser constituted samples is found much higher than in corresponding finer coals.
