Separation and isolation of tantalum and niobium from

Oct 01, 2014· As a result, a flow rate of 1.7 mL/min was selected as the optimum condition to evaluate the total quantitative separation and recovery of Ta and Nb from the other metals in the tantalite ore. Interestingly, a relatively quicker flow rate is the condition which gives better elemental separation

Separation of niobium and tantalum from Mozambican

Nov 01, 2012· 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.
