froth flotation of copper

Jameson cell

Jameson cell

Froth flotation efficiency is determined by a series of probabilities: those of particle–bubble contact, particle–bubble attachment, transport between the pulp and the froth, and froth collection into the product launder. In a conventional mechanically agitated cell, the void fraction is low (5–10%) and the bubble size is large (2–3 mm), which results in a low interfacial area with a ...

INVESTIGATION OF EFFECTIVE PARAMETERS FOR .

porphyry copper flotation is generally controlled by pH. The presence of clay in the ore is the main reason for unstable froths and lowered frothing power. It has been shown that destabilization of frother takes place in the presence of ultrafine particles (Srdjan 2007). It is a common practice that during flotation of porphyry copper ores containing clay minerals, the copper froth becomes ...

Answer. Copper is extracted from copper pyrites by froth flotation process. Froth flotation method is used to separate particles based on the differences in the ability of air bubbles to selectively attach to specific mineral surfaces in a mineralwater slurry. A finely crushed ore is suspended in water and a blast of air is passed through the ...
