SKORPION ZINC: OPTIMISATION AND INNOVATION

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

Leaching of secondary zinc oxides using sulphuric acid

The ore is processed in a sulphuric acid atmospheric leaching circuit, followed by solvent extraction and electrowinning. Zinc casting is used to obtain the 99.995% SHG zinc final product. With Skorpion Zinc’s predicted mine closure date of 2017 approaching, the company is investigating various possibilities for maximizing zinc throughput.
