INVESTIGATION OF DRY COAL BENEFICIATION WITH

2016-10-22  Hence, run-of-mine coal is usually put to the HMS (heavy medium separation) after size classification if necessary. Use of HMS in coal beneficiation has some known operating difficulties resulting from water and magnetite requirement, waste formation, dewatering, and climate challenges. Additionally, HMS plants cannot be constructed in underground.
