Abstract
The effects of Mn2+ on the flotation behaviour of fine refractory antimony oxide and its flotation separation from silicified limestone were studied. The principal gangue mineral, under the condition of pH=7.5 and in the presence of modified water glass through flotability test, measurements of interfacial potential and adsorption, and X-ray diffraction technique were describled. The activation mechanism of Mn2+ in antimony oxide flotation is fully discussed via modern molecular orbit theory.
