allows a pre-concentration step (waste removal at an earlier stage) [3]. Pre-concentrating increases the plant efficiency, because gangue mate- rial is rejected prior to the mineral processing plant and therefore im- proves the downstream processes. Pre-concentration can tip the balance for otherwise nonviable resources.
