SKORPION ZINC: OPTIMISATION AND INNOVATION

2016-2-15  The Skorpion process was developed to treat a complex non-sulphide oxide ore body using atmospheric leaching followed by solvent extraction and electrowinning of zinc (1,2,3) . Sauconite is the largest contributor to the zinc grade with lesser amounts of zinc hydroxides. The gangue minerals are mainly quartz, K-feldspar and muscovite mica. The
