Characterization and Flotation of Sulfur from Chalcopyrite Concentrate Leaching Residue

摘要: Elemental sulfur produced by chloride leaching of sulfide ores or concentrates contains selenium and tellurium usually too high to be used in various industrial agricultural uses. The the residue can upgraded 90% grade froth flotation concentration followed purification removal. is a form discrete particles with size range 5 10 microns. tend agglomerate pulp hence mechanically entrap gangue minerals. With sodium silicate as dispersant well depressant for siliceous material, concentrate recovery obtained single-stage flotation. reagent consumptions are minimum. majority chalcopyrite remains tailings readily recovered different reagents. When amyl xanthate used, 85% copper 14.5% sent back circuits.
