    The trick to maximizing the efficiency of any of these methods is to classify your final concentrates down. Reducing down to approximately -30 mesh will help reduce losses. Anything larger than -30 mesh should be panned out and inspected for larger pieces of gold. Once classified, the black sands can be run through the equipment and yields will be maximized.
