Washability data are very useful for predicting and analyzing the performance of coal preparation plants since most cleaning processes separate coal and rock based on differences in density. Coal Preparation. Figure 1. Float–sink (washability) analysis for a 28.4% ash run-of-mine coal. Full size image.

Fine particle coal is beneficiated in specially designed dense medium cyclones to improve particle acceleration and enhance separation efficiency. Raw coal feed is first sized to remove fine coal particles. The coarse fraction is then separated into clean coal, middlings, and refuse. Middlings are comminuted for beneficiation with the fine fraction.

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).

After crushing, the coal is conveyed to a transfer station where it is sampled by automatic sampler. This sample is reduced in mass from the initial 165 kg by crushing and secondary sampling. The sample not required for analysis is returned to the product conveyor. The sample is collected and analysed every two hours.

The mine run coal is crushed to a size for coking coal requirements. The entire production is treated over a coal jig which removes as waste primarily the coarse refuse. The coarse clean coal passes over the jig along with the fines and is elevated to a wedge bar stationary screen with 1 millimeter openings for dewatering.
