flotation of chromite ore

Rougher flotation of a chromite ore containing abundant serpertine increased the grade form 19 to 41 percent Cr2O3 at a chromite recovery of 89.6 percent. Rougher flotation of ore containing abundant olivine upgraded the chromite from 23.4 to 29.6 percent Cr2O3 at a recovery of 89.4 percent.

ground chromite floated well below the mineral’s PZC with a minor drop in flotation near pH 2. The fresh ground mineral did not generally float well with this collector above the mineral’s PZC although there was a small flotation peak near pH 11.

FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES Seifelnassr, A. A.S* and Tamam, T. A. K** Chromium is one of the most versatile and widely used elements. Its main uses in the a flotation concentrate was obtained containing 52.16% Cr 2O3 and 3.72% SiO 2 with a chromium recovery of 80.0%. Also, Pryor, (1965) reported studies on a Turkish

Actually chromite flotation should be similar to magnetite/ hematite ore flotation. They use amines and a reverse flotation mode.

In the second technique [U.S. Pat. No. 3,473,656], chromite ore flotation is achieved with an undeslimed ore at a pH of 11.5 using a long chain fatty acid collector. The pH of the pulp is adjusted with NaOH with the pulp being dispersed by sodium silicate using carboxymethylcellulose as a depressant for silicate gangue minerals.

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.

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.

Nickel sulphide ore subjected to this investigation was taken from the Marmara district of Turkey, where widespread chromite mineralization can be observed. Some amounts of magnetite and chromite exist in the ore together with sulphide and oxide type nickel minerals. The ore sample contains 1.32% Ni, 10.79% SiO2, 78.39% Fe2O3, 1.3 g/t Ag, and 1.0 g/t Au.

The latter technique has been developed in continuous flotation columns or in other pilot or industrial devices for processing of UG2 ore in South Africa [5 Z. Ekmekçi, D.J. Bradshaw, S.A. Allison, and P.J. Harris, "Effects of frother type and froth height on the flotation behavior of chromite in UG2 ore", Miner.
