Leaching of a low-grade niobium–tantalum ore by highly concentrated
Leaching of a low-grade niobium–tantalum ore by a highly concentrated caustic potash solution was found to be an effective way for the dissolution of niobium and tantalum. The optimum leaching conditions were obtained by mixing the finely ground ore (− 61 μm) with 84 wt.% KOH solution in a mass ratio of alkali to ore of 7 : 1 at 300 °C ...
