Skorpion Zinc is a zinc mine in the ǁKaras Region of southern Namibia, producing Special High Grade (SHG) zinc. The mine is situated near Rosh Pinah. It was established at a cost of US$450 million by Anglo American in 2003.[2][3] It is the tenth-largest zinc mine in the world, and the largest employer in Rosh Pinah, providing 1,900 jobs.[4][5]

Skorpion is a unique mine in several ways. Firstly, it is a supergene zinc ore body composed of alluvial accumulations of zinc carbonate and silicate minerals of detrital nature deposited within a palaeochannel. There are no other currently commercially viable deposits of this type. It is also one of the few mines in the world that currently mines zinc oxides, a mixture of non-sulphidic zinc minerals such as smithsonite, hydrozincite, tarbuttite and willemite. Finally, it is the only zinc processing facility to use solvent extraction-electrowinning metallurgy to process and refine its zinc products (others using conventional smelting and roasting).[6][7]

The Skorpion SX-EW plant creates Special High Grade, ultra-pure zinc cathode as a primary product, which is so low in impurities that it commands a price premium.[8]

In November 2010 the project was acquired by Vedanta Resources at a cost of US$707 million.[9] In 2019, Vedanta announced mining would be suspended for a four months due to technical problems.[10] Then in 2020 Vedanta placed the mine on care and maintenance due to pit failures.[11]
