The Skorpion process comprises three processing steps, atmospheric leaching in sulphuric acid, zinc solvent extraction and electrowinning to produce special high grade zinc. The major mode of impurity transfer was attributed to crud runs in the solvent extraction circuit.
The Skorpion process comprises three processing steps-atmospheric leaching in sulfuric acid, zinc solvent extraction and electrowinning to produce special high grade zinc.
produce special high-grade zinc was realised at Skorpion Zinc using the Modified Zincex TM technology. The essential process comprises leaching, solvent extraction (SX), and electrowinning. The main functions of SX are to provide a barrier against
Skorpion is the largest integrated zinc producer in Africa and the 8th largest zinc mine in the world. It is a conventional open pit oxide mine where the zinc oxide is quarried and then passed through a complex refining and metallurgical process, producing
(Geobiotics). The leaching process takes place in a sulphate medium at low pH. Zinc sulphide is leached by ferric as an oxidant. The ferric is regenerated by oxygen and bacteria. Although it has not been commercialized to process zinc concentrates, the
‘Geocoat’ process from Geobiotics where the zinc sulphide concentrate is coated on an inert substrate before stacked and leached (geobiotics). The leaching process takes place in a sulphate medium at low pH. Zinc sulphide is leached by
the organic stream is loaded to 14g/l. The extraction process results in a zinc delta of 25g/l and generates a sulphuric acid tenor of 35 g/l which is returned to the leaching step in the raffinate. The loaded organic phase is subjected to a three stage counter
Atmospheric acid leaching is utilized to yield a PLS that is forwarded to SX for further processing. The SX circuit is based on a modification of the ZincexTMProcess originally designed by Tecnicas Reunidas for secondary zinc sources2. The selection of SX as a purification step in the Skorpion process was necessitated by a number of factors.
