the overflow is discharged to flotation cells. Air is injected into the flotation cells, and ing agents are added, creating a froth. Copper ore particles, due to their relatively light weight, become a part of this froth, while heavier particles, such as iron ore, do not. The copper-rich concentrate, containing 20 to 40 % copper, is then ...
