Improving Gold Recovery Rates

Alluvial/Placer deposits Again I cannot stress enough the need to get your WT feed size down to 100% passing 2mm and even 1mm for very fine gold areas Any coarse gold can be collected with sluice boxes or gold traps which are very easy to set up It is the fine gold that is difficult to recover — and that is where the WT comes in to play
