  • Before And After Coal Beneficiation

    Beneficiation Of Limestone Wikipedia In South Africa. Coal is sized before and after the beneficiation (cleaning) process. Different cleaning processes are used on different sizes of coal, so that raw coal on entering the coal preparation plant will be screened (sieved) into three or four sizes which then go through to the appropriate cleaning process.
