VANADIUM TESTS: Recoveries top 93% on CMB samples ...

Jul 11, 2010· Agitated acid leach tests yielded the best results with two samples recovering 92.6% and 93.4% vanadium. These tests were performed in agitated glass reaction kettles and carried out at approximately 30% solids at 80°C over a 48-hour period. Recoveries ranged from 13.4% to 93.4% and were found to be directly correlated with acid consumption.

An Overview of the Zincor Process

Abstract - Zincor has been producing zinc since 1969 via the roast-leach-electrowinning process. It is the only primary zinc producer in South Africa, and currently supplies the entire country with zinc. The plant was built by Goldfields of South Africa, on the site of an old gold and uranium mine.
