Flotation of Chromite Ore

2017-6-5  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 concentration by this technique

Flotation of chromite and serpentine - ScienceDirect

2007-6-15  Chromite–serpentine separation was performed applying the froth flotation method, in which chromite was concentrated in the concentrate and serpentine was enriched in the tailings. In preliminary tests, it was found that the modifier should be first added and the pulp conditioned, followed by the collector addition and new conditioning; the obtained difference in results with the two modes was

Recover Chromite by Flotation - 911 Metallurgist

2021-4-6  Flotation can be used to recover chromite from many fine-grained disseminated ore types without prior desliming of the ground pulp. Of the seven samples tested, all but the altered feed to the Mouat fine table section responded to flotation for selective recovery of chromite.

FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES

2014-6-28  The flotation process is typically conducted by adding 0.5 to 5.0 pounds fatty acid, 0.1 to 10.0 pounds soluble fluoride ion and 1.0 to 11.0 pounds sulfuric acid per ton of ore to the aqueous treatment medium containing the chromite ore.

2020-9-25  Flotation process 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.

Chrome Ore Beneficiation Process Chromite

2019-5-15  3.1 Chrome magnetic separation process 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.

Recover Chromite by Flotation - 911 Metallurgist

2021-4-6  Employing the flotation technique described for the George Len, Billie Girl, and Gora ores resulted in concentrates that contained 75 to 84 percent of the chromium at grades of 24.2 to 31.9 percent Cr2O3. Conclusions. Flotation can be used to recover chromite from many fine-grained disseminated ore types without prior desliming of the ground pulp.

Recovery of chromite fines from wastewater streams

The optimal recovery of chromite fines was observed at a pH of approximately 4 for anionic flotation and 11 for cationic flotation. In column flotation tests for the fresh wastewater stream containing 3% chromite fines, a recovery and grade of approximately 40% and 43.5%, respectively were obtained with sodium dodecyl sulphate (SDS) flotation.

Selective Flocculation of Chromite Tailings SpringerLink

2021-1-23  Odisha state is the major reserve of the chromite ore. Due to the extensive applications, high-grade chromite ore is getting depleted day by day. Now it is a challenge for the industry to utilize these low-grade ores and tailings. Several attempts were taken to upgrade the low-grade chrome ores and tailings using different gravity separation methods, magnetic separation methods, flotation, etc.
