with minimum chromium losses, earlier flotation results of lowgrade chromite ores were inferior to those obtained by tabling (Nafziger et al., 1979; Nafziger, 1982). Flotation requires fine grinding, which necessitates high slime losses and creates the slime coating problems, which needs careful reagent control and additional depressing and dispersing reagents. For this reason, finegrained ...

FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES
flotation of lowergrade chromite ores were inferior to those obtained by tabling [Nafziger, 1982]. There are two general types of methods for separating chromium ore (chromite) values from associated gangue minerals by froth flotation techniques. In the first method chromite ore which has been deslimed is subjected to flotation at a pH of to with a long chain fatty acid collector as ...

The entrainment of chromite to the UG2 flotation concentrate adds another challenge to the concentrator operator in that limits are placed on the amount of chromite allowed. Excess chromite in the concentrate results in the buildup of highly refractory chromite spinel layers in the furnaces, thus affecting furnace operation and furnace availability and increasing operating costs (Philips et ...

· It was demonstrated that, when Naoleate is used as collector, chromite, olivine and serpentine can be separated at pH and/or pH when employing ethylenediamine tetraacetate (EDTA) on previously deslimed material. This approach ensures flotation concentrates with a Cr 2 O 3 content better than 50% with a recovery of more than 75%.
