copper oxide flotation

Copper ores Danafloat Home

Copper ores. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance. These are added separately or, as is becoming common, are supplied as blended products to optimize flotation.

flotation of mixed copper oxide and sulphide minerals

Mixed copper sulfide and oxide Froth Flotation (Sulphide Oxide . Sulphides will always float faster than oxides. You float sulphides with PAX and them add your Hydroxamate to get oxides (add NaHS if your material responds to the sulfidiser). In a traditional way, sulphide and oxide copper minerals do not recover at the same rate.

Acid leaching of oxide–sulfide copper ore prior the ...

The aim was to get an insight how high is the copper recovery from the ore, liberated from oxide minerals, in the leaching stage. Potassium ethylxanthate (PEX) was used as a flotation reagent, while as an aero promoter AP 3418 was used, both as collectors, while as a frothing agent DOW 250 was used.

Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Copper Mining and Processing: Processing of Copper Ores ...

Copper Mining and Processing: Processing of Copper Ores. Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit.
