coal preparation cost models domowequlinaria.pl

Costs are divided for technological bocks of coal mining and preparation. Coal production process (as a whole) is expressed in the model by two systems: vertical system that divides a production process into two zones: underground and surface, horizonatal system that divides a production process into three zones: preparatory processes, basic production and activities for production process

One of the ways to reduce coal preparation cost is to investigate all possible plant flowsheets for a given coal and select the one that gives the maximum plant yield. Although, maximum plant yield translates to minimum cost per clean ton for an existing operation, it may not necessarily guarantee
