and Douglas H. Swank was continued in an effort to recover both copper and zinc from commercial brass by an electrolytic method. Such a method would produce metals which would be equivalent to virgin metals in purity. Both Barker and Swank found that such a recovery was possible with brasses containing only copper and zinc

Copper Purification Process Electrolytic Copper Refining

29-12-2017  Electrolytic refining (electrorefining) is a process used to make impure copper pure. Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores. By electrolysis, it can be refined and made very pure—up to 99.999%.

Recovery of copper and water from copper-electroplating

30-05-2011  The results of the EL-ED process showed that almost 99.5% of copper and 100% of water could be recovered, with the energy consumption of EL ≈ 3 kW h/kg and ED ≈ 2 kW h/m(3). According to SEM and EDX analysis, the purity of recovered copper was as high as 97.9%. Copyright © 2011 Elsevier B.V. All rights reserved. PMID: 21466914 [Indexed for MEDLINE]

The purpose of this research was to continue the work of Thomas Parker, who worked on the recovery of copper and zinc from brass during the school year l934 1935. Since there is such a wide variety of brasses made with usually a third alloying constituent, remelt­ed scrap is suitable only for castings of wide tolerance in specifications.

Recovery of copper and zinc from scrap leaded brass

Pure electrolytic copper 99.98% has been recovered from leaded brass containing 60.02% copper, 39.30% zinc and 0.53% lead. Zinc is removed by distillation under vacuum at 1000°C and the residual metal cast into slabs to be used as anodes in electro-refining. The present investigation is confined to the recovery of copper and zinc of high purity from unserviceable leaded brass by partial
