Effect of Milling Method on Chromite Surface Composition ...

2015-4-22  Milling of chromite concentrate is studied in equipment with different milling methods and energy intensity. It is established that milling gives rise to a different chromite fine particle surface structure, different nature and amount of microdeformation within particles, and different chemical activity. Milling has almost no effect on material phase composition. Within a layer more than 50 ...

Potential Toxic Effects of Chromium, Chromite Mining

2019-10-11  By exposing chromite ore to aboveground conditions that promote weathering and oxidation, Cr-III may be converted to mobile Cr-VI. Dry milling (grinding) of chromite ore is now known to convert Cr-III to Cr-VI and efforts are required to avoid producing and spreading hexavalent chromium during mining activity.

2011-4-1  The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr 2 O 3, of Sitampundi area of India, cannot be upgraded by using tabling and flotation techniques, to meet the metallurgical grade due to the intimate association of iron in the lattice of chromite.

The effect of copper sulphate on the zeta potential of chromite was also determined. It was found that collectors alone have an insignificant effect on the flotation of chromite whereas, in the presence of copper sulphate recoveries of above 60% were observed in mildly acid to mildly alkaline solutions decreasing 20% at a pH value of 10.

Characterisation and Pre-concentration of Chromite

2013-12-24  Chromite: Chromite occurs as euhedral to subhedral crystal grains, rarely angular and elongated grains are also noticed. Occasionally chromite grains were fractured. Chromite is more enriched in Fe than normal as alternation product from chromite. Rarely the alteration of chromite leads to box-work type texture (Fig.4e).
