Processing of low grade zinnwaldite (lithium mica

1996-10-1  Zinnwaldite, lithium bearing mica, is obtained as one of the byproduct during the beneficiation of wolframite ore of Degana (Rajasthan). It contains about 0.29 to 0.6% lithium, and some amounts of rubidium and cesium. Initially various processing schemes involving a combination of pyro-hydro techniques were examined.
