Vanadium in slags from smelting of African Pb-Zn vanadate ores: Mineralogy, extractability and potential recovery
Original language description
Slags originating from the metallurgical processing of Pb-Zn vanadate ores at Berg Aukas (Namibia) and Kabwe(Zambia) contain interestingly high concentrations of V (3750–6140 mg/kg) and can be considered potential sources of this metal. Incomplete dissolution of V-bearing clinopyroxene from the Berg Aukas slags, was observed as opposed to the much higher extractabilities of V (> 80percent) in slags from Kabwe. slags. Compared to the relatively high Zn extractabilities (> 72percent), lower yields were observed for Pb due to massive formation of secondary Pb sulfate (anglesite). The Kabwe slags haveRelatively high potential for secondary metal recovery in the future, because they are relatively fine-grained andthe extraction could potentially be carried out on the as-is materials without expensive comminution processes (crushing/milling).
