  60 Centuries of Copper: The Flotation Process

  2018924 · 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 ...

  Adsorption of copper sulphate on PGM-bearing ores and its …

  201661 · In the present study, the effect of copper sulphate on froth stability was investigated on two PGM containing ores, namely Merensky and UG2 (Upper Group 2) ores from the Bushveld Complex of South Africa. Froth stability tests were conducted using a non-overflowing froth stability column.
