    US3857701A Smelting of copper oxides to produce blister

    Blister copper is produced from copper oxides or dead-roasted copper sulfides in a cyclic smelting process using a carbon reductant. In the first stage of the cycle, carbon reductant is added to the furnace charge in stoichiometric excess to form a copper-depleted slag and a molten black copper fraction. The slag is tapped, leaving black copper in the furnace, and a second charge containing ...

    Feb 08, 2021 The concentrate can be effectively smelted when pyrite is replaced by sulfur or gypsum. The copper content of the matte can be substantially increased by substituting gypsum for pyrite. The addition of small amounts of metallic iron to smelting charges containing sulfur or gypsum increases the recovery of both sulfur and copper.
