Copper is one of the major metallic materials together with steel and aluminum. At present, approx. 11 Mt of copper are produced all over the world by electrorefining in sulfuric acid electrolytes. In the last years the current density could be increased to 320-340 A/m 2 by simultaneous improvement of the cathode quality, although the parameters electrolyte and anode quality did not change essentially. This was possible substantially by modifying the cell design, the starter sheets and the… 

Monitoring the Effect of Additive Agents and other Parameters on Copper Deposition by Electro Refining Process

In the electro refining cell the casting anodes were dissolved in the electrolyte solution and the electrical current was applied to deposit the copper as a pure metal on the cathode (Ghodrat et al.,

Copper Refining Electrolyte and Slime Processing - Emerging Techniques

Copper electro-refining (Cu-ER) is the principal method for producing >70% of high or 99.97% pure copper cathodes from 97-99% pure blister/fire refined-scrap copper anodes. While the inert and most

Influence of As, Sb, Bi and O on Copper Anode Behaviour – Part 1: Passivation Characteristics

Copper refining electrolysis is the essential process step to produce high-purity copper and to further concentrate precious metals. The anode copper used in the electrolysis process contains always

Recycling of silver-plated brass for production of high purity copper and ultrafine silver powder for electric contacts

The paper presents an improved process for recycling of silver-plate brass housing. Silver and copper are recovered with a purity of 99.99 % and 99.90 %, respectively, with the aim of obtaining
