GALVANOX™ is a set of methods for leaching copper from concentrates containing a mixture of copper sulphides, but particularly those containing chalcopyrite (CuFeS2).
UBC researchers David G Dixon and Alain F Tshilombo developed the novel process for the galvanically-assisted atmospheric leaching of primary copper concentrates.

Summary Features
- Atmospheric Leach (~80°C)
- No bacteria
- Sulphate based Leach
- No fine grinding
- Generates elemental sulfur (>95%), low oxygen demand
- No surfactants
- Selective for chalcopyrite over pyrite (can cost-effectively treat low grade concentrates down to 9% copper)
- Complete copper recovery, typically in less than 12 hours, and sometimes in as little as 4 hours
- Fully compatible with conventional SX-EW
- Inexpensive to build and simple to operate
- Conventional materials of construction
