What is Dissertation about?
The document discusses the extraction and separation of tantalum and niobium from Mozambican tantalite ore using solvent extraction with ammonium bifluoride and octanol. It examines the effects of decomposition temperature and time, acid concentration, solvent agent, and stripping agent on the extraction process. The optimal conditions were determined and used to achieve high recovery rates of tantalum and niobium. Pure tantalum and niobium oxides were then produced through precipitation and calcination.
