The coal is removed by using a coal extraction technique involving rotary drums that shear coal, shale, and fire clay from the coal seam. After removing large non-coal fragments, water is added to the raw coal to produce a 12 percent coal slurry to separate the remaining shale, fire clay, and other particles from the coal.
Before any of the coal goes into the Affinity prep plant, it comes out of the mine slope and heads into a stacking tube where United can store 50,000 to 60,000 raw tons. Stockpiled raw coal reports to the raw coal silo. That feeds the plant. Then coming out of the plant, Affinity has a 20,000 ton clean coal stockpile area and a 10,000 ton silo.
Those new performance standards were designed to further reduce emissions at new coal preparation and processing plants that process more than 200 tons of coal per day. Coal preparation and processing plants break, crush, screen, clean and/or use heat to dry coal at coal mines, power plants, cement plants, coke …
McLanahan equipment can reduce the amount of fine coal waste that is destined for the settling pond or gob pile by converting it into a dry, drip-free product that is safer and easier to handle. In some cases, these tailings can be repurposed as a saleable product. McLanahan equipment can also help coal producers struggling with an insufficient ...

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e ., ash) from coal. Preparation relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
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.
