Solvent extraction in the primary and secondary

2009-8-27  An unprecedented expansion of the global zinc industry is currentlyunder way. While most new projects and plant upgrades remaincommitted to traditional processing technologies, recent advancesin zinc solvent extraction (SX) have created opportunities for newprocess routes for both primary and secondary materials. The firstcommercial plant to use zinc SX for the mainstream processing of alow-grade ore is under construction and promises to become one ofthe lowest cost zinc producers. Several other oxide and sulphideprojects in various stages of feasibility are considering theinclusion of SX in their process flowsheet. Zinc SX has also provedadvantageous in the reprocessing of secondary materials, partic-ularly for the treatment of zinc residues and furnace dusts. Thisreview focuses on recent installations and projects underdevelopment that feature zinc
