Chalcocite

Tomáš Havlík, in Hydrometallurgy, 2008. 3.2.1 The copper–sulphur equilibrium phase system. The copper–sulphur equilibrium phase system is relatively complicated. Before 1940, only two binary sulphide minerals of copper were known, chalcocite, Cu 2 S, and covellite, CuS. Although it was known that chalcocite forms solid solutions up to the composition Cu 18 S, the mineral …

Copper Smelting

2.1.1.6.1 FeO–Fe 2 O 3 –SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic refractories. Viscosities of slags are important ...

Iodine-assisted chalcopyrite leaching in ferric sulfate ...

Among all oxidants studied (), ferric sulfate is the most commonly used lixiviant because of process simplicity, proven downstream processes, and low capital and operating costs (Watling, 2014; Watling, 2013).However, the dissolution of chalcopyrite in traditional ferric sulfate media at ambient pressure exhibits poor kinetics due to the so-called passivation (Hackl et al., 1995).
