Vulcanization Flotation Of Copper Oxide Ore
In the copper oxide flotation, direct flotation method usually can not achieve better results. Sulfuration flotation method is the main flotation method for treating copper oxide ore and mixed ore at home and abroad. For malachite, azurite, and red copper. Minebased copper oxide ore can get better indiors. The method used to treat the mixed ore is . Vulcanization Flotation Of Copper ...
Recovery of PGMs from an oxide ore by flotation and leaching
enriched in oxide iron minerals as a result of weathering. In the flotation work, the maximum PGM flotation recoveries achieved using the sulphide cocollector schemes were % 3E (Pt, Pd and Au). Appliion of the hydroxamate oxide collector improved the .
Studying on Oxide Copper Ore Flotation with Different ...
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 %, and the recovery rate reached its highest value of %.

· Froth flotation is a method of separating ores using the difference in physical and chemical properties of mineral surfaces. It is currently the main method for the flotation of copper oxide. Relatively speaking, froth flotation can be used to separate malachite and azurite. However, chrysocolla and copper phosphate are difficult to float.

Copper Ore
Sulphidisation – Flotation of Oxide CopperCobalt Ores. Since cobalt is mostly recovered as by product, a typical case of cobalt recovery from oxide coppercobalt ore from Kamwale deposit, loed in Congo is highlighted. Generally such oxide coppercobalt ores are recovered by sulphidisation process.
Flotation of mixed copper oxide and sulphide minerals with ...
· Generally copper oxide minerals do not respond well to traditional sulphide copper collectors and require alternative flotation techniques to concentrate the copper oxides. The classical method involves controlled potential sulphidisation (CPS) to sulphidise the surface of the oxide minerals by the addition of a sulphidisation agent, such as sodium hydrogen sulphide (NaHS).
