Modern coal mines routinely reduce the ash and/or sulfur content of coal to customers` specifications using multistage washeries. Washery configurations are often selected for the particular seam properties and the mining techniques used at a specific mine, as well as the justifiable cost. There is not a single configuration in use for washeries.
