What is coal processing?
What is coal processing?
Coal processing is where raw coal from the mine is cleared using different physical processes, with or without any chemical reagents, to get a product which can be sold in the market or can be used for different purposes such as power generation. Once the coal has been mined it needs to be processed.
What are the four main types of mineral processing?
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.

What are the benefits of coal processing?
The coal washing process, which is usually used for of removal of contaminants, also comes with tremendous environmental and health benefits. It not only reduces the ash content of coal, but also improves its heating value and removes small amounts of other substances, such as sulfur and hazardous air pollutants.
