The 180-or-so papers covered mineral processing, hydrometallurgy, pyrometallurgy, electro-refining
, fabrication, applications and environmental factors, as well as corporate strategies and the economic outlook.
Then the ISA electro-refining process produces high quality copper cathodes in the refinery.
This latest expansion cost $A88 million and included the sinking of the new Robinson shaft, the installation of Australia's largest autogenous mill, additions to the flotation sections, two new CCD thickeners, an electric slag-cleaning furnace, a new anode furnace gas cleaning plant, additional electro-refining cells and new evaporation ponds.
Electrolytic processes account for over 95% of the world's refined copper, with most coming via the conventional route of concentration, smelting and electro-refining
for sulphide ores.
