Column flotation of Montana chromite ore | .

The US Bureau of Mines compared column flotation using either fine or coarse bubbles with conventional flotation on a Montana chromite ore. On deslimed ore, fine-bubble column flotation produced a 44.7% Cr2O3-grade rougher concentrate with 87% recovery, compared with 43.8% and 43.5% Cr2O3-grade rougher concentrates with 85% and 77% recovery for coarse-bubble column flotation .

A Process Mineralogical Evaluation of Chromite at .

A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite. Chromite is a by-product of the Ni-Cu-Co-PGE ore at Nkomati Nickel mine. These being the PCMZ_MG (medium-grade Ni-Cu sulphide silicate ore with disseminated chromite), PCMZ_HG (high-grade Ni-Cu sulphide silicate ore ...

content in the chromite spinel itself. From among the multiple chromite seams of the complex, the UG2 seam has a specif-ically low Cr/Fe ratio together with relatively low Cr2O3 content. The low Cr2O3 content and Cr/Fe ratio inherent in UG2 ore, combine in rendering such ore fundamentally less attractive in its use for the production of ferrochrome
