The Elkington specimen of cathode copper

摘要: ABSTRACTThe specimen of cathode copper dated 1880 in the Percy Collection Science Museum, London was produced world’s first electrorefinery located at Pembrey South Wales, based upon only known application jar-cell technology patented by James Elkington 1869. Drill samples were taken and assayed ICP-MS for a total 23 impurity elements, which 12 considered study. Their average aggregate value about 20 ppm compares very favourably with 23 ppm same impurities typical modern cathode. The silver assay, 2.9 ppm Ag, is low standards, indicating an anode silver, possibly associated levels Pb Sb relatively high As Bi. This unusual combination coupled exceptional purity discussed relation to contemporary conditions Welsh industry.
