Characterization and Flotation of Sulfur from Chalcopyrite .

The flotation reagent consumptions are minimum. The majority of chalcopyrite remains in the sulfur flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of 14.5% in a single-stage froth flotation.
