8.2 Mining and Ore Processing – Environmental Geology

A typical ore body will contain a few percent of ore minerals—typically sulphide minerals like chalcopyrite or sphalerite—along with the minerals of the original rock (e.g., quartz, feldspar, amphibole etc.). Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2).
