Coal Mining Process

The initial step in most coal preparation processes is crushing. The coal, along with all the numerous impurities, is crushed to a powder. The crushed coal is exceptionally light and can naturally try to separate from the crushed material. Once the crushed ROM is placed in water, significantly of the heavier material will sink to the bottom, but the light coal will float on the surface. The water also leaches chemical compounds from the coal powder.

The subsequent step is removing the coal from the water. Soon after the two are separated, the coal is dried and formed into a transportable solid. At this point, the coal is in a usable type and is able to ship to marketplace or move to a firing station for use.

The water containing the impurities along with the water removed from the dried coal is combined into coal slurry. This mixture is normally very toxic and dangerous. Most of the time, a coal preparation plant will have a approach of storing or purifying this water, frequently through evaporation. The harmful material is a common point of discussion when talking about the dangers of coal mining processes.
