mineral processing an overview sciencedirect topics

Mineral processing,mineralbeneficiation, 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 complexprocessingand even by applying extractive metallurgy like hydrometallurgical or pyrometallurgicalmethods

an integrated process for the recovery of tungsten andtin

The complex nature of occurrence of both tungsten andtin mineralsnecessitated an integrated process comprising physical beneficiation and chemical extraction. The process route that was developed gave a tungsten andtinrecovery of about 80 and 90%, respectively, on treating a primary gravity preconcentrate analyzing 16.5% WO 3 and 25.7% Sn
