Treatment of Mixed Sulfide Oxide Ores of Copper

    The first application of sulfur dioxide as a solvent for oxidized copper was by James W. Neill, at Butte, Mont., in the late nineties. Later, a patent was obtained by Neill and Burfeind, on a cyclic process, including the precipitation of a part of the copper from solution as cupro-cupric sulfite.
