The remaining copper holds the precious metals, which are separated out by the electrolytic copper refining process and at the same time concentrated in the anode slimes. Since so many of our members pursue refining as a hobby and thus on a small scale, the beauty of the electrolytic copper process is it can be scaled to work in a tank as small ...
Copper Refineries Pty Ltd is our world-class electrolytic copper refinery in Townsville, North Queensland. Using Glencore's proprietary IsaKIDD process, the refinery produces up to 300,000 tonnes a year of 99.995% pure copper cathode—the primary raw material used to produce copper wire, cabling and many other products we use every day.
