Separation and Concentration Mineral Processing

Gravity Separation is used to separate mineral and gangue with a large difference in their Specific Gravities. Chromite, tin, tantalite and various heavy metals are amenable to this principle. Some gold ores contain Free Gold which can be recovered by gravity separation and this is the traditional method used in artisanal gold mining.
