60 Centuries of Copper: The Flotation Process

The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a froth. Air is pumped into each cell, the solution being agitated to bring froth of bubbles to the surface. In the case of copper minerals, the particles adhere to this froth ...

Improve Copper Recovery – REXA, Inc. Electraulic™ Actuation

Background on Copper Recovery. Copper mining typically encompasses separating sulfide ore and recovery of purer metal particles from gangue minerals using froth flotation. The sulfide ore is then crushed, grinded and milled into fine particles. These fine particles then mix with water into a slurry, feeding into a flotation cell.
