2020-10-20  Chalcopyrite (CuFeS 2) is the major sulphide mineral for Cu extraction, containing about 70 % of total copper reserves globally within all types of copper bearing ore in mineral processing [,, ].The chalcopyrite has to be enriched by flotation, otherwise smelting would not be applicable.

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

Mining Industry Copper Sulfide Ore and Flotation

2019-7-9  (1) Chalcopyrite (CuFeS2) Chalcopyrite (including Cu 34.57%) is the most common copper mineral in China’s copper mines, has good buoyancy. Chalcopyrite is not easily oxidized, and it can maintain natural floatability for a long time in neutral and weakly alkaline pulps. However, in a strongly alkaline (pH>10) slurry, since the surface is eroded by OH-, a hydrophilic iron hydroxide film is
