Column flotation of Montana chromite ore | SpringerLink

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% Cr 2 O 3-grade rougher concentrate with 87% recovery, compared with 43.8% and 43.5% Cr 2 O 3-grade rougher concentrates with 85% and 77% recovery for coarse-bubble column flotation …

Flotation of chromite and serpentine - ScienceDirect

Chromite is an important strategic mineral usually associated with other gangue minerals, mainly silicates. A good knowledge of the flotation behaviour of chromite and the establishment of conditions for its selective separation from the gangue minerals might help the future exploitation of chromite deposits.

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.

Flotation of chromite and serpentine - ScienceDirect

It is well-known that flotation of chromite and serpentine is very difficult, especially in oleate flotation, due to similar surface properties of both minerals and to the ions such as Mg 2+ deriving from the ore and depressing the adsorption of RCOO − ions on the chromite surface . Modifying agents may be used to increase selectivity.

How to Recover Chromite

The objective of flotation studies was to improve the overall chromite recovery by flotation of chromite in the slimes from the gravity concentration circuit. Smith showed that an ore containing serpentine as the primary gangue mineral was amenable to concentration by flotation using a cationic collector with the pH modified to below 2.5 with ...

Extraction of Chromium from Chromite Ore

Chromite Ore Processing. Low-grade ore obtained from an open cut trench at a chromite deposit near Auburn, Calif., was treated in the laboratory using gravity-magnetic separation and flotation beneficiation techniques. Flotation using known methods, however, gave very poor results and will not be discussed further in this report.

Abstract. The Bureau of Mines investigated column vs conventional flotation of chromite and fluorite ores. Fine-bubble column flotation of deslimed chromite ore produced a 44.7 % Cr 2 O 3 rougher concentrate at 87.1 % recovery, whereas conventional flotation produced a 40.4 % Cr 2 O 3 concentrate at 85.4 % recovery. Column flotation of undeslimed chromite ore also …
