  • Perspectives of Reduced Water Consumption in Coal

    2016-10-22 · Abstract. During cleaning of high-ash coal mainly “wet” processes are used which require 5 to 10 tons water consumption per 1 ton of coal. Arrangement of recycling water supply reduces demand in “fresh” water, but transportation of huge volumes of water slurry requires high energy consumption.
