Abstract
Anglo Research (AR), a division of Anglo Operations Limited, is developing a chloride-based processing route for the recovery of zinc from sulfide ores. The Anglo Research Zinc (tARZn) process incorporates a chloride leach. Solvent extraction (SX) is being considered as a potential leach liquor purification option for the process. It is envisaged that the pregnant leach solution (PLS) will be sent to SX after which zinc will be recovered as plate metal and chlorine gas generated from an electrowinning step.
