  • Gravity and Intensive Leach Gold Processing

    Gravity separation has been suggested as an alternative to the use of mercury. However, many sites have pyrite and/or chalcopyrite. The gold is embedded in the ore in very fine particle sizes. That is not amenable to grinding using ball mills followed by gravity separation methods such as sluices or cyclonic concentrations. Consequently, there is a need for simple lowcost methods for leaching ...

  • How to Separate Gold and Black Sands

    I discussed your question with one of my process colleagues in order to get his input on separation of gold from black sands. It can be difficult to get a good separation as the black sands are quite dense. This is even more apparent when dealing with coarse sand and fine gold. I believe the i150 will be setup to run at a maximum speed of 50Hz. The speed can be increased if necessary but keep ...
