Gangue rejection is the process of separating and disposing the poorest, low-quality, low-value material in an ore feed prior to further downstream processing. Simply put, the focus is on the waste to reject, rather than the mineral to recover. Economic benefits are gained when the gangue volume is replaced with useful material of a higher grade.
