    The ore types most suited for treatment by this scheme are those consisting of sands, residues from gravity plants, and others of an essentially deslimed nature As with most conventional flotation procedures for chromite, desliming was a requisite to mineral selectivity and recoveryChromite is an important strategic mineral usually associated with other gangue minerals, mainly silicates A good knowledge of the flotation behaviour of chromite and the(PDF) Flotation of chromite and serpentine

  • Flotation of Chromite Ore

    Chromite mineral liberation in all ore samples was essentially complete at sizes finer than 65 mesh The collectors used in flotation testing are listed in table 3The objective of flotation studies was to improve the overall chromite recovery by flotation of chromite in the slimes from the gravity concentration circuitHow to Recover Chromite

  • Chrome ore beneficiation challenges & opportunities – A

    Since most chromite ores are easily beneficiated with gravity concentration methods, flotation of chromite has not been widely applied or got commercial acceptance (Atalay and Ozbayoglu, 1992) This is the most essential issue of every gravity separation circuit in mineral processing plants, which causes loss of large fraction of the valuableFlotation 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 slurryFive Chrome Extraction Process to Teach you the Chromite
