    Apr 03, 2017 That the furnace refining of copper is superfluous in so far as it improves the grade of marketable copper has been shown by the experiments of E. Keller. As a result of these experiments Keller states that “electrolytic copper which has not been melted and refined is superior in conductivity to the refined and cast copper by over 2 per cent
