Fundamental surface chemistry and froth flotation behavior using quebracho tannins
MetadataShow full item record
With an increasing emphasis on minimizing the impact and downstream treatment of metallurgical processes, a focus on utilizing less harmful and easier to handle reagents is occurring. Tannins, a naturally occurring, non-toxic reagent, have shown promise in metallurgical and mineral processing applications. This research was performed to investigate the use of tannins (specifically two types of quebracho: Tupasol ATO and Tupafin ATO) in the froth flotation process as a depressant for gangue minerals. Two ore types, copper and fluorite, were researched. The primary gangue mineral of interest was ...
