Looks to me like the specific gravities of chromite and magnetite are too close for gravity separation. Flotation collector 3418A was used for the nickel fraction and the grind is …

Chromite is an important strategic mineral usually associated with other gangue minerals, mainly silicates. 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.

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

The physico-chemical interactions among minerals such as olivine, chromite and serpentine; the most commonly present ions in solution such as Ca and Mg; and flotation reagents such as EDTA and oleic acid were investigated. The study was conducted via release tests, electro-phoretic measurements and microflotation of selected minerals coming from the Kukes deposit in Albania. The …

3.2.. Effect of metal ions on flotation of chromite finesChromite is a spinel mineral with a chemical composition of (Fe, Mg)O, (Cr, Al, Fe) 2.Although the theoretical composition of chromite is FeO·Cr 2 O 3, magnesium can easily substitute for iron ions, while aluminium and ferric ions commonly substitute for chromium.. Surface properties and hence the solubility characteristics of chromite ...

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.

The US Bureau of Mines compared column flotation using either fine or coarse bubbles with conventional flotation on a Montana chromite ore. On deslimed ore, fine-bubble column flotation produced a &.7% Cr2O3-grade rougher concentrate with 87% recovery, compared with 43.8% and 43.5% Cr2O3-grade rougher concentrates with 85% and 77% recovery for coarse-bubble column flotation …

Flotation can be considered as a leading process to beneficiate the fine chromite which cannot be enriched by gravity separation. Because of the complex nature of chromite and olivine which is the most abundant adjoininig

The Bureau of Mines, U.S. Department of the Interior, devised a flotation technique for upgrading chromite in chromium ores and gravity concentrates. The technique consisted of cationic flotation of chromite from a slime-free pulp acidified to ph 2.5 Or lower using h2so4 modifier. Flotation results showed that ore containing serpentine as the primary gangue mineral was more amenable to concentra

In December 2020, Eurasian Resources Group (ERG) reported that its Kazakhstan headquartered subsidiary, Kazchrome, had successfully completed trials for the use of floatation technology in the recovery of chromite from tailings at the Donskoy Processing Plant. Trials of the novel floatation technology resulted in a chromium oxide recovery of 55%, with the specifications of the …

Flotation of Chromite Gravity Concentrate. The amine flotation method was applied to chromite gravity concentrates prepared from Benbow-2 ore by a combined Humphrey's spiral and table separation technique. The purpose of re-treating the gravity concentrate was to prepare a low-silica feed material for refractory testing.

The flotation of chromite from "slime fraction" of the gravity circuit of Kemi concentrator, Finland was studied. The main gangue minerals are chlorite, tremolite and talc. Amines or fatty acid collectors are normally used for this sort of mineral composition. Theoretically, a sufficient selectivity should be expected in the region where ...

Yes, gravity separation is the way to go in case of chromite. If there are other valuable species, e.g. PGM-containing minerals, they can be floated first and then tails go to gravity separation. Actually chromite flotation should be similar to magnetite/ hematite ore flotation.

(WHIMS), a rougher, scavenger and cleaner flotation cell was used for the flotation experiments. The flotation circuit is shown in Figure 1. The tailings obtained from a chromite recovery circuit were conditioned in a condition tank using 40g/t of the frother and 200g/t each of the collector and depressant.
