Separation of Chromite from Serpentine in Fine Sizes using ...

In this study, possible separation of chromite from serpentine in fine sizes using a magnetic carrier was investigated as a function of pH, dodecylamine (DDA) dosage, and amount of magnetite. First, the zeta potentials of minerals were determined in the absence and presence of DDA, and then magnetic carrier experiments were performed in conditions based upon the zeta potential results.

US3146091A Method and process for the extraction of ...

The reduced serpentine is not magnetic to the extent that reduced laterite is. The magnetic separation is not applicable on serpentine ores. The magnetic characteristics of reduced laterite is due to magnetite, Fe O formed in the reducing roast. Under my specified roasting conditions, there is no reduction to metallic Fe, but to Fe O only.

SELECTIVE FLOCCULATION BEHAVIOR OF CHROMITE AND …

Conventional techniques, such as gravity concentration, magnetic separation and flotation, are generally ineffective in treating slimes. Thus, slimes are usually ... selective flocculation to chromiteserpentine mixture using starch, in a similar fashion to the selective flocculation of iron oxidesilica system, was explored.
