Potential Benefits of Underground Processing for the Gold

Traditional surface processing for gold recovery is designed to achieve recovery through 'whole ore leaching' This involves grinding 100 per cent of the ore into sub 50 - 75 micron particles The Python relies on coarser grinding (much cheaper) and preconcentration of the gold-bearing minerals rather than liberation of the gold itself Get price
