FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES

chromite and serpentine. Olivine, iron oxides and talc have been identified as minor minerals. Adequate degree of liberation of chromite was obtained by grinding the ore to minus 180µm. Froth flotation was used to upgrade this chromite ore. Oleic acid was used as collector. Several operating parameters influencing the floatability of the Sudanese chromite ores were investigated. These include ...

Effect of serpentine and sodium hexametaphosphate on ...

instance, it is found that fine particle serpentine has adverse effects on flotation of nickel-bearing pyrite and chromite [6,7]. Because of the difference on surface charge, fine serpentine particles can be adsorbed to the nickel-bearing pyrite and chromite easily, which leads to a low recovery of target mineral [8]. Sodium hexametaphosphate (SHMP) is found to be a good inhibitor to ...
