Separation of niobium and tantalum from Mozambican

2012-11-1  Highlights Tantalite ore was digested using molten ammonium bifluoride. Niobium and tantalum were extracted using octanol as extractant. Addition of H 2 SO 4 improves the separation of niobium and tantalum. Extraction with 2-octanol is almost similar to extraction with 1-octanol. Two and three stages were sufficient for the extraction of Ta and Nb respectively.
