Leachox

There are several process alternatives to Leachox™ for the treatment of refractory flotation. Processes such as roasting, pressure oxidation, and bacterial oxidation are all aimed at breaking down the sulphide matrix to liberate gold. Ultra-fine grinding performs the same function particularly where gold is locked in silicates or other minerals.
