deposits in the Rosh Pinah region, consideration is given to convert the Skorpion Zinc refinery to process zinc sulphides. Concentrates can also be imported via Luderitz harbor, approximately 400 km from Skorpion Zinc. Leaching kinetics of zinc sulphides are significantly slower than those of oxides,

The leaching kinetics of a zinc sulphide concentrate in .

This work examines the dissolution kinetics of an iron–rich zinc sulphide concentrate in acid ferric sulphate medium. The effects of temperature, ferric ion and sulphuric acid concentrations, agitation speed and particle size on the leaching kinetics were investigated. The leaching process could be separated into two stages.

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.

process at Skorpion will therefore increase the business risk. Having the primary business linked to another market, especially a by-product market, will be a disadvantage. The pyrometallurgical and RLE processes will therefore be discarded as options for Skorpion Zinc. There are two options when the percolation leach process is considered.

The leaching, solvent extraction and electrowinning (LX-SX-EW) process is a widely used method in the production of copper from low-grade oxidized ore. Copper is the most common metal to be processed by LX-SX-EW, but the process can also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.
