Abstract
The treatment of anode slimes at Outokumpu Pori Copper Refinery comprises the following process stages: copper leaching by air oxidation, nickel removal by digesting slimes in concentrated sulphuric acid at 200 °C, and dissolving of the formed nickel sulphate into water, roasting of the slimes in controlled gas atmosphere at 600 °C for selenium removal, smelting of slimes in a Doré furnace, electrolytic refining of silver, sulphuric acid and aqua regia leaching of slimes from the silver cells followed by the reduction of gold and platinum metals. The paper discusses operational experiences and recent developments of the process.
