Coal Processing CHPP Design With over 30 years experience in coal preparation, engineering and design, our teams have the critical expertise to make meaningful contributions to the future strategy of preparation plant and mining operations.
First, the coal goes to a preparation plant where it is washed or cleaned to remove contaminants. The cleaning removes impurities like rock, ash, sulfur and other substances. A high amount of rock and clay particles reduces the quality and heating value of coal and usually means a lower price for coal. ... Coal processing involves crushing ...

With coal preparation, raw coal is cleaned using different physical processes, with or without any chemical reagents, to get a product which can be sold in the market. Coal preparation process starts with crushing and screening of freshly mined coal, which removes some of the noncoal material.
These preparation plants generally crush the runofmine coal to minus 6inch pieces prior to processing. The finer material, less than 1 mm, is often cleaned by frothflotation techniques. The waste from this process is deposited in slurry ponds.
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
The scheme used in physical coal cleaning processes varies among coal cleaning plants but can generally be divided into four basic phases: initial preparation, fine coal processing, coarse coal processing, and final preparation. A process flow diagram for a typical coal cleaning plant is presented in Figure
