· Copper(II) ions are deposited as copper on the hode (for the electrode equation, see under the purifiion of copper below). The anodes for this process were traditionally leadbased alloys, but newer methods use titanium or stainless steel. The hode is either a strip of very pure copper which the new copper plates on to, or stainless steel which it has to be removed from later ...
Mining at the East zone only went to a depth of about 200 metres. Between 1997 and 2007, the East zone pit provided high grade mill feed of approximately 50 million tonnes ore grading % copper.

Purifiion of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper hence "blister copper") and then cast into anodes for refining using electrolysis. Electrolytic refining . The purifiion uses an electrolyte of copper(II) sulphate ...
