Separation of concentrates often performed prior to chemical processes Solid-liquid separation used everywhere. Typical Beneficiation Steps Beneficiation the enrichment of ores and separation of unwanted gangue minerals .mined coal or reducing the associated ash or both. Two basic processes of beneficiation Dry-deshaling Non-coal or shaly-coal is removed without using any liquid media. Wet process Coal is crushed to smaller size and put in a liquid media of adjustable specific gravity to separate the lighter coal low ash from heavier coal high ash.Raw coal fed on to the vibrating bed having crosswise and vertical slope. Air supplied through air holes in the beneficiation bed which agitates the raw coal resulting in stratification of coal as per its relative densities -lighter coal forms the upper layer and heavier coal forms the lower layer.
