: The effect of surface potential on the flotation of chromite
The flotation was also found to favour the recovery of chromite particles with high chrome to iron ratio. The experiments showed a distinct abundance between the chromite surface charge and the selectivity as well as reversible adsorption-desorption behaviour. This confirms the hypothesis of physical adsorption of fatty acids on chromite at low pH.
