  • Flotation of Chromite Ore

    Collector adsorption and thus chromite flotation at pH 2 is probably due to sulfate ion from the H2SO4 acting as a bridge between the positive amine and positive chromite surface. Effect of Collectors on Flotation of Chromite Ore. Four different amine collectors were investigated using the 16.3- percent-Cr2O3 Benbow-1 ore.

    Flotation Studies on Gangue Minerals. Hallimond tube flotation studies on chromite ore gangue minerals were performed. The particular minerals studied were olivine, diopside and hedenbergite. The initial flotation conditions are indicated in Table VII. Under such conditions, although less than expected, olivine flotation was satisfactory.

  • 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

    Actually chromite flotation should be similar to magnetite/ hematite ore flotation. They use amines and a reverse flotation mode. Rahil Khan. 4 years ago. Rahil Khan 4 years ago. Like. I'll probably try PGM float than gravity separation. I believe we have the reagents available here. The stone size are coarse, the particle size needed for

  • Flotation ore dressing Britannica

    Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

  • 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.

    flotation performance (Shortridge et al. 1999; Dalvie et al. 2000). The objective of this research was to determine the level of copper sulphate dosage that can activate the chromite and also to evaluate the effect of the depressant type and dosage on the recovery of chromite in the flotation of UG2 ore. The

  • Column Flotation of Chromite and Fluorite Ores

    Column flotation of undeslimed chromite ore also produced results superior to those attained with conventional flotation. Column flotation of fluorite ore produced a 90.9 % CaF2 rougher concentrate at 86.8 % recovery, compared with a 67 % CaF2 rougher concentrate at 90.4 % recovery produced by conventional flotation.
