De Wet and Singleton, 2008, Gnoinski, 2007 used the Skorpion sulfuric acid leach/solvent extraction process to extract zinc from nonsulfide ores in which the silica was successfully precipitated by adding CaCO 3. Unfortunately, iron cannot be easily eliminated from the organic phase in solvent extraction. Contact Supplier
The synergist mixture was successfully tested in the Tati demonstration plant that used a processing route similar to that employed at Bulong to treat a sulfide concentrate feed material. The Skorpion Zinc operation in Namibia is the world''s largest minetometal zinc operation that produces 150 000 tpa of special highgrade zinc.
Finally, it is the only zinc processing facility to use solvent extractionelectrowinning metallurgy to process and refine its zinc products (others using conventional smelting and roasting). The Skorpion SXEW plant creates Special High Grade, ultrapure zinc hode as a primary product, which is so low in impurities that it commands a price

The Skorpion Zinc Project involved the development of a greenfield zinc mine and refinery. At Skorpion, oxidised zinc ore is mined from an open pit and refined into special high grade zinc ingots on site. The project was initiated by Reunion Mining Namibia (Pty) Ltd and a feasibility study, including an Environmental Assessment, was
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The quality of Pregnant Leach Solution (PLS) at Skorpion Zinc is of utmost importance for efficient operation of the Solvent Extraction (SX) Plant. Suspended solids in the PLS forms CRUD in the settlers, resulting in reduced zinc transfer capacity and increased impurity carry over to Electrowinning.
