The beneficiation of tailing of coal preparation plant by ...

2018-9-17 · Dense-medium cyclones have been used for beneficiation of fine particles of coal. In this study, the usability of cyclones in the beneficiation of tailings of a coal preparation plant was investigated. For this purpose, separation tests were conducted using spiral concentrator and heavy medium cyclones with the specific weight of medium 1.3–1.8 (g/cm3) on different grading fractions of ...

Improving energy efficiency of cyclone circuits in coal ...

2014-4-15 · 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 pumping systems.
