Surface chemical mechanisms of inadvertent recovery of ...

The flotation rate of coarse chromite correlates with the exposures of magnesium and silicon in patches on the chromite surface; higher exposures give earlier flotation. Conversely, there is a negative correlation with signals corresponding to the chromite surface, i.e. Cr, Fe, Al. Flotation of chromite without collector has confirmed this statistical discrimination. Hydrophobic talc-like ...

Mineral Processing and Extractive Metallurgy Review

The ore sample is constituted of about 70% magnetite, 15% sulphide minerals, and 5% chromite and iron oxides, as well as 10% gangue minerals. Nickel mineralization in the ore such as pentlandite, violarite, millerite awaruite, and asbolanewas determined. Due to the complex structure of mineralization, a combination of gravity-separation and flotation methods was applied for the concentration ...

Chromite and talc are two major gangue minerals in platinum bearing UG2 ore processed from the Bushveld Complex in South Africa. During flotation, talc is effectively depressed by the addition of depressants.

Effect of Slimes on Iron Ores Flotation - sapub

The presence of slimes is, in general, harmful to the flotation of iron ores, affecting the selectivity and the quality of the concentrates, besides causing an increase in reagents consumption. This work describes the behavior of different iron ore types from the Iron Quadrangle, Brazil, with respect to desliming in hydrocyclones and flotation, including a study on the dispersion degree as a ...

Chromite is one of the main gangue consituents of UG2 ore and it is essential that the amount of chromite reporting to the concentrate during flotation be minimised since it is detrimental to the subsequent smelting operations. It is generally considered that chromite is naturally hydrophilic and only reports to the concentrate by entrainment. However, it is possible that, under certain ...

How to Recover Chromite

The objective of flotation studies was to improve the overall chromite recovery by flotation of chromite in the slimes from the gravity concentration circuit. Smith showed that an ore containing serpentine as the primary gangue mineral was amenable to concentration by flotation using a cationic collector with the pH modified to below 2.5 with sulfuric acid (H2SO4).
