    Copper Mining and Extraction: Oxide Ores

    Solvent Extraction and Electrowinning (SX-EW) production, virtually non-existent before the 1960s, reached nearly 3.8 million tonnes of copper in 2013. (Courtesy of ICSG.) One of the biggest advantages of using leaching is that low grade ores that would be uneconomic to smelt become economic to leach. This is largely due to the much lower energy costs of leaching and also to the lower capital

    Electrolytic Copper Refinery Using the Moore Industries

    The copper is then stripped from the stainless steel mother plates and the copper is shipped as melting stock to mills or foundries where it is cast into wire rod, billets, cakes, or ingots, as pure copper or is alloyed with other metals. The impurities, or tank house slimes, leftover after the electrolytic refining contain a range of other valuable minerals including gold and silver which is

    Current Distribution in Modern Copper Refining

    The copper industry was based essentially on the use of a copper starter sheet as the substrate for the refined copper deposition. In the 1970's operating current densities with this technology were typically around 220-250 amps per square metre. There was a clear recognition that the maintenance of electrode spacing or geometry was crucial in minimising short circuits and rough growth within

    How Hydrometallurgy and the SX/EW Process Made

    The SX/EW process has provided the copper industry with a tool that makes the extraction of copper from its ores significantly more environmentally friendly than by the use of the conventional smelting process. While the SX/EW process was adopted by the industry to take benefit from the sulfuric acid that the smelting process produced steps are being take to divorce the two. The Phelps Dodge
