THE FLOTATION OF A GIBBSITIC BAUXITE ORE

Marino S, Wang X, Lin C, Miller J

Efforts are now being made to develop improved flotation technology for the efficient processing of low grade bauxite ores. Such resources are classified according to the primary bauxite mineral (gibbsite, boehmite, or diaspore) and according to gangue minerals (quartz, clays, iron oxides, etc.). The flotation response of gibbsitics bauxite ores with and without desliming is discussed with respect to flotation strategy, mineralogy, and liberation characteristics.
