the overflow is discharged to flotation cells. Air is injected into the flotation cells, and foaming 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 copperrich concentrate, containing 20 to 40 % copper, is then ...

Coarse gangue rejection essentially uses flotation cells as an ore sorting technology. "It's an ore sorting technology, except it sorts material at maybe half a millimeter, as opposed to conventional sensorbased ore sorting, which decides whether a 6in. rock can be differentiated and disposed of before it goes through the plant," Wasmund explained.
