text: In addition to its use in recovering silver in lead refineries, the BBOC has been used to treat anode slimes from copper electrolytic refineries.
  Anode slimes are composed of solid particles that do not dissolve in the electrolyte in the refining cells. This includes the gold and silver present in the copper anodes that are being refined. As with recovering silver in lead smelting, reverberatory furnaces are often used in the copper refining industry for the purification and recovery of gold and silver from anode slimes. However, the reverberatory furnaces suffer from similar disadvantages in copper anode doré production as they do in lead refineries, including resulting in a large inventory of gold in the system.  Other furnace types used, include top-blown rotary converters  and short rotary furnaces.
