Abstract

A method includes separating, in a first stage of separating, crushed ore material by size into a first fines stream and a first coarse stream; grinding the first coarse stream in a second stage of grinding; feeding the product of the second stage of grinding back to the step of separating; feeding the first fines stream from the step of separating to a recovery circuit; producing a rejected stream from the recovery circuit of crushed ore material that does not meet the target mineral size; separating, in a second stage of separating, the rejected stream from the recovery circuit into a second fines stream and a second coarse stream; grinding the second coarse stream in a third stage of grinding; and feeding the product of the third stage of grinding back to the recovery circuit.
