Improve coal quality and reduce emissions of coal-fired pollutants. Coal washing can remove 50%-80% of ash and 30%-40% of total sulfur (or 60%~80% of inorganic sulfur) in coal.


The coal washing factory in Tiefa Mining Bureau was built and put into use in 1969. After three times of extending and improving, now its washing and separating capability is 1,400,000 t/a, with 400,000m3 water slurry to discharge every year. The quality of the coal washing wastewater is presented in Table 1. Table 1.


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).
