flotation of chromite ore

Flotation of Chromite Ore 911metallurgist Petrographic examination of the pH 2.0 flotation products showed olivine to be present in the concentrate while serpentine remained in the tailings. To increase the selectivity of Mouat ore to amine flotation of chromite, a selective olivine depressant must be found.

flotation of chromite ore

The flotation behaviour of chromite with respect to the. Flotation behaviour of chromite with respect to beneficiation of UG2 ore Zeta potential measurements Zeta potential measurements were determined On the chromite without reagent addition and thereafter in the presence of 1 x 10-4 M copper sulphate (the highest concentration of copper sulphate used in the microflotation tests).

The flotation behaviour of chromite with respect to the ...

Chromite is one of the main gangue consituents of UG2 ore and it is essential that the amount of chromite reporting to the concentrate during flotation be minimised since it is detrimental to the subsequent smelting operations. It is generally considered that chromite is naturally hydrophilic and only reports to the concentrate by entrainment.

The Bureau of Mines, U.S. Department of the Interior, devised a flotation technique for upgrading chromite in chromium ores and gravity concentrates. The technique consisted of cationic flotation of chromite from a slime-free pulp acidified to ph 2.5 Or lower using h2so4 modifier. Flotation results showed that ore containing serpentine as the primary gangue mineral was more amenable to concentra
