    Hard Rock Mining ApplicationsAlluvial Mining, Placer Mining DredgingUpgrading Sluice ConcentratesProspecting / Drilling / Bulk SamplingAlluvial miners often ignore the fine gold because sluices and jigs can’t catch it. Depending on the size and shape of your gold a sluice may begin to lose gold at 40 mesh. Some alluvial mining deposits have 90% of their gold finer than this where enhanced gravity, iCON, is the only solution. Concentrators are being tested on the ends of sluices and s. In this case the operation is still capturing the same amount of gold in the sluice. The added value of the concentrator becomes very clear. After seeing the
