Chromite Flotation MetallurgistMineral Processing

Flotation recovery of chromite as a function of pH at constant SDS concentration 1 x 10 -4 M is shown in figure 2. The four separate curves of the figure demonstrate the effect of aging of dry chromite that had been ground to flotation size (100/150 mesh) on subsequent flotation behavior. The fresh

Chrome Ore Beneficiation Process Chromite Processing

The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite.

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
