Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed …

Besides the caustic consumption reduction, the beneficiation plant decreases the refinery energy consumption and residue generation amount, as the overall bauxite quality is improved with the removal of the reactive silica. To select suitable equipment and technologies, it is necessary to properly characterize the bauxite.

Mineral beneficiation equipment from Multotec utilises cyclones, magnetic separators, spiral concentrators and flotation components. Multotec has refined these solutions through over 40 years of equipment provision to the global mineral beneficiation industry reflecting continuous research and development.

The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques.
