coal beficiation is manufacturing or not

Chapter 7 COAL - Pennsylvania State University

A method of beneficiating coal in a dry process includes separating raw coal from a coal mine into coal fines and larger pieces of coal using pressurized air, separating the larger pieces of coal according to size, removing ash from the larger pieces of coal on an air table, and further removing ash from the larger pieces of coal using a size-discriminating device to obtain a beneficiated coal ...

Coal preparation plant - Wikipedia

The current turbulence in the mining industry in South Africa has its roots in several different factors. First, the fall in global demand for platinum and other minerals due to recession; second, the consequences of the Marikana disaster in destabilising labour relations; and third, the structural character of our mining industry. A great deal has been written about the first two factors, so ...
