Skorpion Zinc - Vedanta Zinc International

The US$200 million Pit 112 expansion currently under way has increased Skorpion’s reserve and resource to 26Mt (3Mt zinc) and extended the life of mine from 2017 to 2020. Refined zinc production in FY2018 is expected to be approximately 90kt, rising to approximately 130kt in 2020.

Skorpion Zinc - Wikipedia

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 and opened in 2001. It is the eighth-largest zinc mine in the world, and the largest employer of Rosh Pinah, providing 1,900 jobs. Skorpion is a …

Skorpion Zinc Mine - Mining Technology | Mining News and ...

Zinc processing. Skorpion is the first commercial application of zinc SX-EW for processing primary leach liquor. Crushed ore is homogenised and wet milled. The refinery comprises basic zinc sulphate production, SX, EW and melting / casting facilities. Sulphuric acid leaching takes place in agitated tanks at atmospheric pressure and elevated temperature.

SKORPION ZINC - Vedanta Zinc International

SKORPION ZINC: A JEWEL IN THE DESERT 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 special high grade (SHG) zinc.


The Skorpion process comprises three processing steps, atmospheric leaching in sulphuric acid, zinc solvent extraction and electrowinning to produce special high grade zinc. The


The plant will operate by applying Modified ZINCEXTM Process (MZP) Technologies to the previously mentioned raw materials of zinc. The MZP is Técnicas Reunidas’ proprietary technology, which has been completely developed and industrially tested, and has been working successfully for over 10 years in the SZ plant. It is based on the selective leaching of raw

J Skorpion Zinc - SciELO

The Skorpion Zinc process produces high quality zinc at relatively low operating costs. It produces a 99.995% Special High Grade (SHG) zinc product2, using a zinc oxide concentrate due to the oxidized ore reserves present in the region.


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 …

The Skorpion process comprises three processing steps-atmospheric leaching in sulfuric 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.

2013 The Modified Zincex Process - Técnicas Reunidas

Modified Zincex Process by Técnicas Reunidas Figure 6: Skorpion Zinc plant Technical Advantages The main differential advantage of MZP over RLE comes from the existence of two independent circuits that lead to safer and more robust operation; one circuit for leaching and another for electrowinning.

Skorpion zinc solvent extraction: the upset conditions

Skorpion Zinc became the first mine-to-metal operation to commer-cially apply a purely hydrometallurgical process route to exploit a zinc oxide orebody. The novel technology, known as The Modified ZincexTM Process patented by Tecnicas Reunidas, comprises sulphuric acid atmospheric leaching, zinc solvent extraction (SX)


At Skorpion, the metallurgical process is unique and the plant design requires minimal fluctuations within a selected feed grade. In addition, the presence of limestone inter-fingered with ore in some areas of the deposit results in dilution problems which may increase gangue acid consumption and therefore processing costs. Hence, selective
