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.

2 content increasing from 49 to 75% as the mineral oxidises and iron is leached out by groundwater. Altered ilmenite (60-75% TiO 2) is usually amorphous, but the leucoxene (76-90% TiO 2) stage begins to show the definite crystalline structure of rutile. The name "pseudorutile" has been proposed for ilmenite alteration products containing 75 ...

Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
