  • A Recirculating Sluice Box for Gold Prospecting 10 Steps

    The gold in the crushed ore was rather large and chunky and there was virtually no black sand in it I had expected the sluice to do well with the ore A more real world test would be to see how it handles fine gold mixed with black sand like what it would be seeing if I fed it gold bearing stream gravel.

  • Pressure oxidation

    Pressure Oxidation is a process for extracting gold from refractory ore. The most common refractory ores are pyrite and arsenopyrite which are sulfide ores that trap the gold within them.Refractory ores require pre treatment before the gold can be adequately extracted The pressure oxidation process is used to prepare such ores for conventional gold extraction processes such as cyanidation.
