Innovative Copper Refining Process

The innovative ISA process developed by Mount Isa Mines Limited (MIM) for the electrolytic refining of copper was first implemented by Copper Refineries Pty. Ltd., Townsville in 1979. The process features the use of permanent stainless steel cathode plates and an associated cathode copper stripping machine. The permanent stainless plate is made from 3.25 mm thick 316L stainless steel and is welded to a 304 stainless steel hanger bar which is copper plated to provide the necessary electrical conductivity. An extrusion of acrylic PVC is used as side-edge masking together with a sacrificial seal of high melting-point wax. Dipping in the same wax provides masking for the bottom edge of the plate. This edge protection system, together with operating know-how, is the technical innovation and ensures that the copper cathode deposit will not dislodge during normal handling but will readily strip from the stainless plate in the stripping machine. The ISA Process has been most successful and has been licensed in Australia, Austria, Canada, Mexico and the USA.
