This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground engaging tools. ROM coal can have a large variability of moisture and maximum particle size. Handling
The four stages in coal formation are peat, lignite, bituminous and anthracite. Each of these stages must be completed for coal to form. Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide. When a plant dies, and stays under water, it builds up an accumulation of peat.
