Copper extraction

Froth flotation. All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite ), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution,

Concentration of Ores Hydraulic Washing, Froth Flotation

Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of minerals and gangue.

Copper Mining and Processing Processing of Copper Ores

After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and worthless rock, called gangue (pronounced gang). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

OVERVIEWHISTORYINDUSTRIESPRINCIPLE OF OPERATIONSCIENCE OF FLOTATIONFLOTATION EQUIPMENTFroth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuRead More

Why is the froth flotation method only used for sulphide ores?

Feb 17, 2018Answer Wiki. In froth floatation process, advantage is taken of prefferential wetting of ore particles by oil and gangue particles by water. Pine oil or eucalyptus oil has tendency to wet metal sulphides. Thus sulphide ore is present in oily froth whereas gangue particles settle at the bottom,and hence fuller concentration is achieved.
