• waste, i.e. waste rock grains. The plant where processes are carried out to remove impurities, admixtures and excesses in order to increase the share of coal in the unit of volume (or weight of the extracted mineral) is the Mechanical Coal Processing Plant (ZMPW) (Bielewicz et al., 1993). The basic functions of ZPMW include:
A coal fired power plant with a yield of 33% (which is the world average for these plants) will use roughly 400 kg of coal to produce one electric MWh. If ashes represent 20% of the incoming weight, we will get roughly 80 kg of ashes. 1 TWh électrique (one million MWh, or one billion kWh) means 400,000 tonnes of coal used, and 80,000 tonnes of ...
