— The black copper produced during reductive smelting contains an appreciable quantity of zinc, lead, tin, nickel, and iron. These species detrimentally impact the electrolytic refining process and are removed in the converting stage. The zinc, lead, tin, and iron can be reduced to low levels, but only a portion of the nickel can be removed.

This document describes an experiment simulating the industrial electrolytic recovery of copper from brass. Students conduct electrolysis using a brass anode and copper cathode in a copper sulfate/sulfuric acid solution. Copper is deposited on the cathode while zinc remains in solution. Students calculate current efficiency and can estimate the zinc …

 — A new process for recycling zinc and copper from the smelting slag of waste brass was investigated in this study. The zinc and copper present in the smelting slag were dissolved in a ZnCl 2 –NH 4 Cl solution system. To recycle copper, the lixivium was purified by a novel method termed as electrochemistry and chemistry synergetic (ECS) purification.

This experiment offers an opportunity for students to simulate in the laboratory an electrochemical process with the aim of obtaining pure copper from scrap brass plate. An additional (optional) part of the experience would be a more precise quantification of the brass and the copper deposit composition by means of atomic absorption spectroscopy.

Electrolytic refining. The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper(II) ions are deposited as copper. At the anode, copper goes into solution as copper(II) ions.

 — Nesbitt and Xue, 1995 pointed that the presence of copper sulphate with dissolved oxygen in sulphuric acid is the most successful leachant for the recovery of metals viz. zinc, copper, lead from brass foundry wastes.

Electrolytic recovery of copper from copper-zinc sulfate solutions obtained by hydrometallurgical treatment of brass ashes and flue dusts has been studied by Duman et al. (1989). It was revealed that Zn 2+ ions cause grain size reductions of the cathodic copper in relatively high copper electrolytes.
