Additional Physical Format: Online version: Ulke, Titus, b. Modern electrolytic copper refining. New York, J. Wiley & Sons; London, Chapman & Hall, limited, This chapter highlights that electrolytic refining is the principal method of mass producing high-purity copper. Copper from electrorefining, after melting and casting, contains less than 20 ppm impurities, plus oxygen which is controlled at –%. Table of ContentsStudies in Refining Electrolytic CopperRefining-Charge No. 1Refining-Charge No. 2Summary of Refining-Charges Nos. 1 and 2Studies in Overpoling Electrolytic Copper The object of refining copper in the reverberatory furnace is to obtain a metal which will have the highest attainable degree of malleability, ductility and electric conductivity, and present at the same time a level. Electrorefining of Copper 1. Electrorefining – General Introduction The major use of copper in modern times has been as an electrical conductor, and Diagram showing the structure of the cells in which the electrolytic refining of copper is carried out.

Grant, in Encyclopedia of Materials: Science and Technology, Electrolytic Refining. The Betts electrolytic refining process generally uses an aqueous electrolyte of hydrofluorosilicic acid (H 2 SiF 6) at a concentration of 90– gl −1, lead at 70– gl −1 and a temperature of 40 °C. Alternative electrolytes are sulfamic acid (HSO 2) and fluoroboric acid (HBF 4). Under the influence of the applied electrical potential, copper ions migrate from the anode and deposit on the cathode, forming cathode copper. Electrolytic refining of copper was first patented in England by James Elkington in and the first electrolytic copper refinery was built in . In refining copper, an aqueous solution of copper(II) sulphate is electrolyzed, using impure copper as the anode and pure copper as the cathode. At the anode, metal impurities higher than copper in the electrochemical series such as zinc, iron and lead are oxidized first, then copper loses its electrons to form copper(II) ions.
