The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded (purified) by flotation technology.

At present, we can use the flotation process to recover the chromite with fine grain size (-100um) after the gravity separation. The results show that Mg2+ and Ca2+ can inhibit the chromium ore, and the inhibition of Mg2+ is influenced by the type of anions in the slurry. In the flotation experiments, chromite separation from olivine has been tested on three industrial olivines produced in Norway, differing from their particle size distribution, and kindly supplied by Sibelco (France): GL30 grade, GL10 and GL30 Milled (the last one being obtained from GL30 by milling).

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 typical product obtained by such a process, from an ore containing 25.2% Cr 2O3, is a recleaner concentrate containing 41.0% Cr 2O3 and 2.5% SiO 2 with a chromium recovery of 77.0%. In the second technique [U.S. Pat. No. 3,473,656], chromite ore flotation is
May 23, 2014 The selective flotation of chromite minerals of any chromite ore have some difficulties due to dissolved cations from He found that all amines with HCl and NaOH gave satisfactory . evaluation of a separation process such as flotation practice. It is well HAVENS, R. Froth Flotation Of Chromite Ores. Read more
Generally, in the beneficiation plants, the as-received low-grade chromite ores are upgraded to high-grade chrome ore by crushing and grinding, followed by different classification units and gravity separator units, i.e. spirals, tables, etc., for further beneficiation. The rejects from different circuits are reported as plant tailings [ 2, 3 ].
In a flotation process, the ore is typically crushed and wet ground to obtain a pulp. The main alternative technique in froth flotation is "reverse flotation. fluorspar, iron ore, chromite, scheelite, CaCO2, MgCO2, apatite, or ilmenite. dosage of other more expensive collectors in the amine flotation of KCl.
The degree of separation of chromite in oversize fraction of 37 mu m is 58%. From the measurement of zeta-potentials with various pH, it can be said that the zero point of charge (ZPC) of chromite is pH 7. 4. Below the ZPC chromite is positively charged, so it shows a high floatability by the addition of anionic sodium dodecyl-sulfate. Above
The general flotation method was developed by Havens. Deslimed chromite ore was floated at pH 1.5 to 5.5 using a long-chain fatty-acid collector and soluble fluoride ions as a silicate depressant. The Havens method was later modified slightly to permit flotation without preliminary desprm. 3.1 Chrome magnetic separation process The chrome 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.
