Development of a viable process for the T recovery of zinc ...

The Skorpion Zinc Project demonstrated the viability of the production of zinc from non-sulphide (commonly called 'zinc-oxide') ores, using the leach/solvent extraction/electrowinning process route. The success of Skorpion raised the profile of a number of other zinc oxide deposits, considered to be similar.

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

Solvent extraction in hydrometallurgy

Skorpion flowsheets are discussed. Solvent extraction (SX) is a process by which closely related elements or com-pounds in solution are separated based on the differences in partitioning of the species between two immiscible phases. In the SX process the species of interest is typically extracted from an aqueous phase into an organic phase.

Leaching (chemistry) - Wikipedia

Leaching is the process of extracting substances from a solid by dissolving them in a liquid, naturally.In the chemical processing industry, leaching has a variety of commercial applications, including separation of metal from ore using acid, and sugar from sugar beets using hot water.Leaching also occurs on its own in nature; for example substances leaching from plants due to rain, dew, mist ...

The leach kinetics of zinc sulphides is vastly slower than oxides, preventing the processing of zinc sulphides using the existing process, under current conditions. The challenge for Skorpion Zinc is to identify a suitable zinc sulphide treatment process that can be integrated with the existing plant.
