GALVANOX^TM 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.This new process achieves virtually complete copper leach recovery typically in as little as twelve hours, is effective with low grade concentrates, reduces SO₂ gas emissions and eliminates the costs of transportation to the smelter.

The University of British Columbia's University-Industry Liaison Office has put together a testing and licensing package for interested parties.
