Copper removal from molybdenite concentrate by sodium

The purification of molybdenite concentrates by this method is feasible, and the best results were obtained by leaching the concentrate with the stoichiometric concentration of H 2 SO 4 and 0.12 M Na 2 Cr 2 O 7 solution for 90 min at 100176;C. Under these conditions, about 95% of the copper was dissolved with little dissolution of molybdenum.
