A concentration of 25–30% is suitable for economical smelting of copper. The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now

May 16, 2016 Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter

Nov 05, 2018 Copper Sulfide Flotation. Coal is somewhat unique in that it constitutes the major component of the pulp and is the floated species. The possibility exists that the froth generated in coal flotation coincidentally agrees with the mechanical model. Copper sulfide ore, being more dense and with floatable valuable material of about 1% or less, is
