A Mine Flotation of Chromite Ores from the Stillwater

2018-3-28 · 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 concentration by this technique than ore containing the readily flotable olivine as the primary gangue mineral.

2019-9-16 · It appears, then, that the manner in which the chromite ore is treated prior to flotation is of substantial importance in subsequent flotation. Even how long the ore has been stockpiled prior to flotation is likely to be of importance. Among the gangue minerals studied (olivine, diopside, hedenbergite, bronzite) it appears that olivine is the ...

Flotation of chromite and serpentine

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.

A selective froth flotation process for the treatment of chromite ores having low grade chrome spinels, zircon, staurolite, ilmenite, magnetite, garnet, quartz, epidote, olivine and alteration products as inclusions, which comprises subjecting a pulp of such an ore to an initial blunging treatment in the presence of a soluble iiuosilicate ...
