Coal Beneficiation plant – VSRL Energy & Resources

Coal beneficiation plant is the removal of soil, rock and dirt, Ash from Run-of-mine (ROM) coal through washing and separation processes. Coal beneficiation makes the resource more economically profitable by improving its quality and also contributes to lower transport costs by reducing waste products.

Coal Beneficiation - an overview | ScienceDirect Topics

The hard coal beneficiation process in mechanical preparation plants generates coarse, small or fines rejects and coal tailings slurries. The tailings are the finest grain size, with the majority below ~ 0.25 mm, whereby material sized below 0.035 mm makes up to 60% share in the slurry composition.
