Page ID. 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 …

The beneficiation rate of titanium oxide slag can be up to 70% 76%. (2) The fluxes play critical role for separation of iron from slag. Especially, adding Li2CO3 by 2% 3% can decrease the separation temperature by about 100 'C. (3) The main phase of beneficiation slag is the solid solution phase of M3O5 type called as anosvite.
