  • SEPARATION OF CHROMITE FROM OLIVINE BY ANIONIC

    2003-11-17 · Separation of chromite from olivine by oleate flotation is poorly understood because of the variable compositions and physicochemical properties of both minerals. Chromite as a spinel mineral, consists of two and three valency metal oxides (XO, Y2O3). Although X2+ and Y3+ are generally iron (II) and chromium (III), magnesium is substituted to the ferrous ion while ferric and aluminium ions are substituted for chromium. Flotation of Chromite as Pre-Treatment of Olivine ,The flotation method has been developed after addition of 3.3 wt% M4 chromite to GL 30 olivine particles to magnify the possible separation of the two minerals by flotation. Because of the presence of chromite in GL30 olivine, the initial content of 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.MINERAL PROCESSING BEHAVIORS OF CHROMITE ,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.
