Improving energy efficiency of cyclone circuits in coal beneficiation
In the dense medium cyclone (DMC) coal beneficiation process, only 25% of the pumped medium are used by the DMC while the other 75% simply flows back the corrected medium tank without being used. Therefore, there is a great opportunity for reducing energy consumption of the DMC coal processing plant by energy-efficient …

Coal Beneficiation Technology
Coal Beneficiation. Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the 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.
