Coal mined from the Talcher region of Odisha, India is known to be high-ash, surface-oxidized, and noncoking in nature. It is quite challenging to beneficiate such low-grade coal by physical or physicochemical processes due to its oxidized nature and the presence of complex ash forming mineral matter in its matrix. Chemical beneficiation is one of the alternative process to such problems

Raw coal may be sold as mined or may be processed in a beneficiation/washing plant to remove noncombustible materials (up to 45% reduction in ash content) and inorganic sulfur (up to 25% reduction). Coal beneficiation is based on wet physical processes such as gravity separation and flotation. Beneficiation produces

Jun 28, 2021Briquetting of Coal. Fine clean coal concentrate obtained after flotation test was filtered to remove water and then dried in electric oven at 105 o C to get rid of moisture and flotation reagents. It was mixed with appropriate amount of binder in a trough mixer to make briquettes of about one inch.

The present study was carried out to beneficiate coal tailings sample using froth flotation technique. The aim of the investigation was to remove the carbonaceous material present and to reduce the environmental pollution generated through large volume of tailings from a coal preparation plant. The characterization studies show that the sample contains DSUB80/SUB passing size as 276 and

Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).
