Smelting low Pyrite Copper Concentrate

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.
