· Clean coal a viable option due to latest advances in finecoal beneficiation. The shift to mechanised mining in the coal industry has had the sideeffect of an excessive quantity of fines being produced, which often means that the thickeners deployed in mineralsprocessing circuits are undersized and cannot cope.

Among the fine coal cleaning methods, the oil agglomeration process has important advantages such as high process recovery, more clean product, simple dewatering stage. Several coal agglomeration studies have been undertaken recently and effects of different variables on the process performance have been investigated. However, unlike flotation studies, most of the previous agglomeration ...

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).

Coal–oil–water (COW) fuels. When fine coal is beneficiated by flotation, for example, the wet fine coal need not be dried but may, after filtration, be blended with oil. An ultrasonic treatment after grinding and mixing gives a very stable COW slurry. The need for any stabilizing additives is eliminated.
