This laboratory study investigates selective grinding and beneficiation options for a Greek bauxite ore. First, a series of batch grinding tests were carried out in order to investigate the grinding behavior of the ore and the effect of the material filling volume (fc) on the distribution of aluminium and ironcontaining phases. Then, the ground ore was subjected to magnetic separation either ...

Feb 15, 2012 · The processing or beneficiation phase is generally grouped in a specialised unit (called "concentrator") used to separate the mineral phases containing the useful substances from the waste gangue; the product of the plant, enriched with useful materials, is called the "concentrate". In most cases, the concentrate is the marketable product.

The beneficiation of domestic ferruginous bauxite to obtain a bauxite suitable for refractory use was investigated. Ferruginous bauxites are domestically abundant but they are not adequately utilized owing to their low alumina and excessive iron content. This report describes tests using highintensity, wetmagnetic separation of flotation concentrates to reduce the iron content.
