Kesterite
Beneficiation of such ores is difficult since stannite behaves similar to pyrite and other sulphide minerals during various processing stages (Benzaazoua et al., 2003; Xu et al., 2012). Cassiterite occurrences in placer and hard-rock deposits are very distinct. Hence, different mining methods are employed for the extraction.
