Sulphide Flotation - an overview ScienceDirect Topics

Where there is no constraint on concentrate quality, high gold and sulfide flotation recoveries are achievable to the extent that a discardable gold flotation tail is possible (Bax and Bax, 1993; O'Connor and Dunne, 1991). Cleaning-circuit configuration, either single or two stages of cleaning, and cleaner residence time are related to the particle size of the sulfides in the flotation feed and the presence or

Characterization and Flotation of Sulfur from Chalcopyrite ...

2013-12-24  (d) Chalcopyrite flotation on tailings of sulfur flotation. The tailings of sulfur flotation conducted at close to neutral pH with pine oil, kerosene and sodium silicate as the frother, the collector and the dispersant, respectively contain about 4% copper and 10% sulfur. Quartz is the major component in the tailings. Copper in the mineral form of chalcopyrite in the tailings was tested for flotation. The copper flotation tests were conducted at about 30% solid by weight, 10g/t of pine oil, 10 g/t of copper sulfate and 25 g/t of potassium amyl xanthate. The pH of the pulp was adjusted to about 7. The result of chalcopyrite flotation on the tailings of sulfur flotation
