Effect of particle size on the surface oxidation and flotation behavior of galena particles in lime system

In this research, the effect of particle size on the surface oxidation and flotation behavior of galena in the lime system was studied. Coarse (−0.074 + 0.038 mm), intermediate (−0.038 + 0.025 mm) and fine (−0.025 mm) galena particles were used in the experiment. The dissolution tests, flotation tes...

Summary:In this research, the effect of particle size on the surface oxidation and flotation behavior of galena in the lime system was studied. Coarse (−0.074 + 0.038 mm), intermediate (−0.038 + 0.025 mm) and fine (−0.025 mm) galena particles were used in the experiment. The dissolution tests, flotation tests, and sorption tests were accomplished. Through further analysis by XPS, the effect of particle size and lime was observed. The decrease of mineral particle sizes increased the adsorption ratio of collector and the dissolution of galena, while the hydrophilic product OH − /Ca(OH) + produced by dissolution occupied the dominant position, which led to the minerals hydrophilic.
