chromite - an overview | sciencedirect topics

Wet high-gradient magnetic separation is usually thought to be the most promising method for improved performance. Chromite ore can be separated in a high-strength field, despite the presence of iron impurities. The choice of method depends on several factors, primarily the type of the gangue

characterization and beneficiation of anka chromite ore

characterization and beneficiation of anka chromite ore

The samples assaying 36.84% of Cr2O3 was subjected to beneficiation process in order to enrich the ore, in terms of the Cr2O3, using magnetic separation. The results obtained after the analysis of the beneficiated ore using wet chemical analysis and Atomic Absorption Spectrometer shows that Cr2O3 content increased to 48% with a maximum Cr:Fe ratio of 6.2:1

co2 sequestration by carbonation of olivine: a new process

co2 sequestration by carbonation of olivine: a new process

Various mechanical operations can be considered for the separation of chromite from olivine as magnetic or gravimetric separation [ 8, 9 ]. Flotation of chromite, based on surface phenomena, has been extensively investigated for the recovery of fine particles in the range 25-100 μm [ 10, 11 ]
