MAGNESITE BENEFIATION METHODS: A REVIEW

Abstract

ABSTRACT. Magnesite is one of the most important mineral commodities mostly because of its technological and industrial applications. The most important commercial sources for its recovery are the corresponding ores. The deposits are characterised by the differences in reference to magnesite mineral crystallinity and gangue composition. For these reasons, the separation efficiency of magnesite from gangue varies from relatively easy to impossible. Another problem is the stocked waste, often of relatively high–grade in magnesite, derived from industrial processing, which may be viewed as future potential deposits. This paper contributes a detailed review on the methods applied to separate magnesite from gangue both on industrial and bench scale; potential processing methods for fine particle size are also reviewed.
