While revenue streams from coal are largely in US dollars (USD), operating costs such as labour, railway ...
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 11.10-1.

Coal receiving to a preparation plant is carried out without a proper charge, corresponding to the design specifications. Second – size degradation is not taken into account during the delivery from the mine (open cast) stock dump to the coal preparation plant. Raw coal breakage takes place at the mine (open pit) stock dump on the way from the
Fraser Alexander is specifically focused on washing coal on a contract basis for coal mining clients. It has the capacity to provide the operation and maintenance (O&M) of existing wash plants; or to build, own, operate and maintain (BOOM) or build, own, operate, maintain and transfer (BOOT) the wash plants.
In fact, the coal is washed when it is beneficial to do so, and the optimum operating conditions chosen for washing are decided on a cost basis. While taking up this exercise, it was immediately realized that the solution to the cost versus quality problem came from two aspects: technological and economics vis-à-vis optimum ash level of the ...
