Hofirek and Kerfoot, 1992, Fugleberg et al., 1995 among others have investigated the reactions that take place during leaching of nickel-copper matte in a sulphate environment. The typical major phases of copper sulphide leach residue are covellite and digenite (Cu 9 S 5) for copper, and millerite (NiS) and polydymite (Ni 3 S 4) …

Carbon may also be left in the metal as an impurity. Sometimes this can be removed afterwards (for example, in the extraction of iron); sometimes it can't (for example in producing titanium), and a different method would have to be used in cases like this. Other more reactive metals can be used to reduce the ore.
