THE CHALLENGE OF COAL PREPARATION

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.

Coal Preparation Plant Advancements - Mining USA

Ultrafine Coal Cleaning Recent studies have found that spirals such as the SX7 can provide an effective gravity-based separation performance for -100 mesh coal. Required volumetric flow rate is around 15 gpm/start and feed solids content should be nearly 15% by weight. Currently, two U.S. coal preparation plants use spirals in this application.
