  • Yukon innovation increases gold recovery for placer

    Placer gold ranges in size from finer than 74 microns (200 mesh) to coarse nuggets depending on the source of the gold, size and gradient of the stream and many other factors Sluiceboxes are the primary means of concentrating the low grade alluvial gravels and can provide relatively efficient concentration (in excess of 95% recovery efficiencies) at high ratios of concentration (20,000:1).
