Nov 05, 2019· Since impure coal is so detrimental to its use, most coal mining companies own or use a coal preparation plant In most cases, these plants remove the impurities and process the coal to a standard size and grade for shipment Coal that comes directly from a mine is called run-of-mine (ROM) coal This is a very impure substance
With coal preparation, raw coal is cleaned using different physical processes, with or without any chemical reagents, to get a product which can be sold in the market Coal preparation process starts with crushing and screening of freshly mined coal, which removes some of the non-coal material
One of the introduced landforms is the "wet refuse impoundment," a structure designed to store the waste from coal preparation plants At the Goals Preparation Plant in Sundial, an AT Massey subsidiary, coal from surrounding mines is cleaned through a process called "flocculation," which separates ash from coal, making the coal lighter to .

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships
Coal preparation is a specialisation in the field of minerals technology All coal contains some non-carbonaceous mineral matter both within the coal itself and added during the mining process (often unintentionally) where roof or floor is cut or breaks and mixes with the cut coal
