Pressure leaching of decopperized copper electrorefining anode slimes in strong acid. 467 leaching was conducted for two hours thereafter the autoclave was cooled down to the room temperature and the leach residue were removed for filtration and washing. Experiments were performed as a full factorial test in order to determine the effect of
Electrolytic copper refining plantopper electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing cuso4 and h2so4, and selectively electroplating pure copper from this electrolyte without the anode impuritieswide range of high quality standard equipment customised projects.
Abstract. In electrolytic refining, the plates of crude metal are anodically dissolved in a suitable electrolyte, while "pure" metal is deposited on the adjacent cathodes. The electrorefining process was introduced about a hundred years ago to produce a substitute to firerefined copper. Today, practically all of the world's copper production...
indicated that the production of electrolytic copper was about 13,066 kilotonnes per year of which about 2,375 kilotonnes per year proceeded from electrowinning operations. Recent advances in hydrometallurgy led Mount Gordon Operations of Western Metals Copper Ltd., Australia to treat some copper sulphide ores directly in an autoclave reactor.
