The Tailings Center Mining Engineering

After extraction and beneficiation, the residuals from mineral recovery are normally discharged as a hydraulic fill (aka slurry) composed of finely ground gangue (sub-micrometer to sand-sized particles), chemicals, and process water into a TSF impoundment where solids slowly consolidate, releasing water much of which is returned to the

Mineral Processing an overview ScienceDirect Topics

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
