Anthracite

Anthracite, also known as hard coal, is a hard, compact variety of coal that has a submetallic luster has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 98%.

Coal preparation plant

Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).
