Samples of pyrite concentrate were studied in the plant central research laboratory and this demonstrated the presence within it (on average) of 80% pyrite, 4.7% chalcopyrite, 1.5% molybdenite, and 9.8% quartz. Pyrite is mainly in the form of disseminations in quartz and chalcopyrite, and rarely encountered veinlet accumulations with a size of ...
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.
