Coal Beneficiation Process Diagram - 911 MetallurgistMar 17, 2017 . The fine coal, along with clay and its high ash fractions and water averaging 15 to 18% solids, discharges by gravity into a (Patented) Super Agitator and Conditioner. Kerosene and pine oil are added and the conditioned slurry or pulp then is introduced into the “Sub-A” Coal Flotation Machine. The low ash.Coal Beneficiation Technology 2007: Initiatives, Policies and PracticesTwo 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). The rejects from wet process also.
