Knowledge of the chromium ore minerals proper and their associated rocks-forming minerals is needed to explore new chromite fields and to predict the efficiency of individual methods for the beneficiation of chromite ores. It is important also to know the physicochemical properties of individual mineral fractions of chromite ores and …
Reduction Smelting of Red Mud . Red mud is the so-called bauxite residue after the solid–liquid separation from alkaline high-pressure leaching of aluminum bearing bauxite ore. Depending on the composition of the primary mineral deposit, 4–7 tons of bauxite are necessary to yield 2 tons of alumina in order to produce 1 ton of aluminum.
