Flotation Process Of Chromite Ore

  • Flotation of Chromite Ore

    2017-6-5 · Effect of Collectors on Flotation of Chromite Ore. Four different amine collectors were investigated using the 16.3- percent-Cr2O3 Benbow-1 ore. The FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES,2014-6-28 · There are two general types of methods for separating chromium ore (chromite) values from associated gangue minerals by froth flotation techniques. In the first method chromite ore which has been deslimed is subjected to flotation at a pH of 1.5 to 5.5 with a long chain fatty acid collector as reported by Havens (1946). The selectivity of the process is enhanced by adding a soluble fluoride compound such as hydrofluoric acid, sodium fluoride or sodium silicofluoride in the flotation medium. 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.

  • The effect of copper sulphate addition on the recovery of

    2009-8-27 · Chromite and talc are two major gangue minerals in platinumbearing UG2 ore processed from the Bushveld Complex in SouthAfrica. During flotation, talc is effectively depressed by the additionof depressants. Chromite, on the other hand, is considered to behydrophilic, its recovery is believed to follow water recovery andtherefore recovered by entrainment only. In certain cases it hasbeen shown that chromite can be activated by the reagent suite andhence is made amenable to true flotation. The aim of the work wasto investigate the effect of the addition of copper sulphate as anactivator and the effect of the depressant type and dosage on therecovery of chromite. The results of these experiments showed thatcopper sulphate, at higher dosages, activated the chromite. Lowdosages of copper sulphate resulted in no chromite Flotation of chromite and serpentine ScienceDirect,2007-6-15 · A beneficiation process of chromite ore was published, for the flotation of olivine (i.e. magnesium iron orthosilicate) by dodecylamine ; with this, however, the chromite concentrate appeared to have a low grade due to serpentine, which was following chromite and did not float.
