froth flotation process for extraction of copper

Cu-Pb Froth Flotation Guidance - Mining-pedia

May 24, 2022The froth flotation process is mainly used to separate non-ferrous metals such as copper, lead, zinc, nickel, gold, etc. In addition, froth flotation is suitable for the separation of fine particles that are difficult to recover by other beneficiation methods.

Separated ore is passed to aeration tanks where reagents are added that bind and trap the copper sulfide particles to the reagent. Air injected by valves from the bottom of the tank forms a froth on the top of the tank. The froth, rich in copper, is mechanically skimmed from the tank for downstream processing.

The froth of copper-rich bubbles at the top of the tank is then skimmed off for further processing. The gangue sinks to the bottom of the tank to be removed or disposed of as mine tailings. The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners.

Flotation Froth - an overview | ScienceDirect Topics

Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles ( Fig. 17 ). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.

Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
