Conventional coal preparation plants account for about 25% of the cost of the total surface facility. The coal preparation plant cost may comprise 5-15% of the cost of a coal mine. A thermal dryer installation may cost 25-30% of the cost of a coal preparation plant. The cost of coal cleaning itself may be 15-25% of the cost of mining the coal.
Why is Coal Preparation Needed? • Coal preparation is required because freshly mined coals contains: i) Heterogeneous mixture of organic (carbonaceous) matter. ii) Inorganic (mineral) matter. • These impurities reduce coal heating value, leave behind an undesirable ash residue. • Increase the cost of transporting of coal to market.
Supposing the unit time cost of preparation of each kind of coal in coal preparation plant is almost the same, the scheduling model can be translated into solving a set of appropriate Km, X1, X2 and X3 to pursue the maximum economic benefits. There is the following mathematical programming.

The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...
What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal …
CRF Circulating Water: The water of the whole coal preparation plant needs to be recycled, because the water cost much in a wet coal preparation plant, Usually the repeated utilization rate of water needs to be more than 90%, and the unit supplementary water quantity is less than 0.15m ³/ t (raw coal).
The main driver of corrosion cost is the structural steelwork used in buildings and mechanical equipment support framework. The majority of these costs are derived from the coal preparation building. The second corrosion costs driver was the replacement of water and air pipework.

relevant cost components, including the coal preparation cost. One way to reduce coal preparation cost, which is expressed on the basis of cost per ton of clean coal, is to increase the amount of clean coal recovered from a given amount of raw coal without adding to the total cost incurred in the preparation of that coal.
