Taking the maximum economic benefits of coal preparation plant as a target, we established the mathematical model of the scheduling process. 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
In comparison, the current wet coal preparation plant serving the Prairie Eagle Mine provides a clean coal yield in the range of 60 to 67% at a product ash of ~9.5% (on a dry basis) and a product sulfur content of ~3.25% (Stanley, 2012).
A coal preparation plant takes coal from a mine and cleans it for transport. When coal comes out of a mine, it is full of impurities. These impurities lower its overall value, reduce its usefulness and increase the cost to ship it. Since impure coal is so detrimental to its use, most coal mining companies own or use a coal preparation plant.

• Cost estimation of the identified plant options 2.1 INFORMATION GATHERING Cost estimates have been derived from local and international sources and from PB's in-house data including those of PB Power. A complete list of references is included at the end of this report. In order to identify thermal peaking plant cost estimates, PB has relied on:
Thus there is a considerable margin for operating costs in a fine flotation cleaning method that will materially lower the ash of the cleaned coal. Further convincing evidence that ash removal from coal is of major importance is found in the weekly magazine of metal working, Steel, January 29, 1951, reporting on a modern coal preparation plant.

According to Coal Age's 2013 Prep Plant Census, the U.S. currently employs 288 coal preparation plants to beneficiate coal. A prep plant by definition is a facility that upgrades coal through a washing process that removes ash and other impurities.
Coal preparation plant means a facility where coal is crushed, screened, sized, cleaned, dried, or otherwise prepared and loaded for transit to a consuming facility. "Coal preparation plant associated areas" means the coal preparation plant yards, immediate access roads, coal refuse piles, and coal storage piles and facilities.
The preparation plant is still under construction, but the coal handling and rail load-out facility has been completed and is currently processing coal. NRP expects that approximately 35 million tons of coal will be processed through this facility during its life.
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 preparation…
Coal Preparation Plant. A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Coal preparation plants prepare various types of coal in response to market demand. Three types of preparation plants are common: (1) "complete preparation," those that clean both coarse and fine coal; (2) "partial preparation," those that clean only coarse coal; and (3) "coal crushing," where the coal is merely crushed to a specified maximum size.
