Various collectors and combinations of them were used for experimental study on flotation of oxide copper ore in Huidong and the results showed that isoamyl xanthate would be a proper collector agent. When using it at 550g/t, the rough concentrate grade was 3.97%, and the recovery rate reached its highest value of 83.05%

Get PriceFeb 26, 2017 Oxide Copper Flotation. Flotation of oxide copper ores finds its most wide use in the Congo and Rhodesia sections of Africa. Malachite is the copper mineral recovered by Flotation in these areas. Flotation of these ores presents both mechanical and metallurgical problems which, by careful analysis by the metallurgists in charge, have been overcome
Get PriceThe traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation, which was first developed with industrial success on Pb–Zn oxide ores in Australia (Crozier, 1991). The method involves multistage addition of sodium sulphide (Na 2 S), sodium hydrogen sulphide (NaHS), or ammonium sulphide (NH 4) 2
Get Priceore after sulphidisation showed a copper deportment of 0.1 % cuprite, 0.6 % malachite, 0.8 % chalcopyrite and 84.8 % chrysocolla, suggesting that all oxide copper minerals present in the LQ ore, except chrysocolla, are amenable to flotation using SIBX after sulphidisation. This
Get PriceFlotation is suitable for copper-oxide ores with relatively complex ore properties and composition. Flotation methods for copper-oxide minerals tend to be divided into direct flotation and sulfidization flotation , , . In direct flotation, minerals are floated by direct addition of collectors and frothing reagents without activating agents or
