By the ratio of chromium and iron in chrome spinels, it is possible to assume the efficiency of industrial use of ores. For the ores of the Ammonal ore occurrence, the ratio of chromium to iron corresponds to 1.8–3.1, and for the ores of the Vodorazdelny ore occurrence −1.9–2.8, which allows them to be used in the chemical industry (with ...

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 of water and ...
