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). A R

C.R. Ward, in Reference Module in Earth Systems and Environmental Sciences, 2013 Size separation. Most of the techniques used in coal cleaning are effective only with particles falling within a certain size range; many markets also have size distribution requirements. The crushed coal is usually separated into size classes by a process in which it is

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.

Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.
