enhancement of dry beneficiation of coal by air

Jun 26, 2021 Therefore, before using for combustion, coal is subjected to physical (wet/dry) beneficiation, which uses physical property difference (e.g., density, surface property) between macerals and mineral matter for enhancing calorific value of coal. Dry beneficiation has advantages over wet beneficiation in terms of environmental concerns and economic aspects
