Characterization of Physico-Chemical Changes during the Alkali Roasting of Niobium and Tantalum Oxidse two metals in minerals. Traditionally, niobium and tantalum mineralsare digested using hydrofluoric acid at moderate temperatures, producing oxy-fluorides which are separated by solvent extraction, involving the use ofhazardous chemicals. The increasing environmental pressures are forcing the ind
