ABSTRACT. Skorpion Zinc is located 25km North West of the small settlement of Rosh Pinah in southern Namibia. Commissioned in early 2003, Skorpion Zinc became the first mine-to- metal operation to commercially apply a purely hydrometallurgical process route to exploit a zinc oxide ore body.

· Neither Ionquest 290 nor Cyanex 272 extract Al, Cu, Mn, or Ca significantly. Ionquest 290 recovery of Zn is 5–10% higher than Cyanex 272. In addition, 20%(v/v) Ionquest 290 produces higher recoveries than 40%(v/v) DEHPA, thus Ionquest 290 has been selected as the most suitable among the extractants studied.
