Experiments were carried out on 35 kg melts of doped cathode copper and anode copper in a 3 m 3 , 150 kW vacuum induction furnace. Rates of removal of bismuth, arsenic, and antimony were measured over temperature and pressure ranges of 1450 to 1610 K and 3 to 30 pascals, respectively. Bismuth removal was found to be rapid: 1 to 18 x 10 >-5 m/s.
