ABSTRACT:
The known process of separating molybdenum from a tungsten-molybdenum containing alkaline solution has been improved by carrying out the chemical reaction between the solution treated with sulphuric acid and an added sodium bisulphide solution in a continuous process within a multi-stage stirred-tank reactor system, whereby the freed hydrogen sulphide is recycled for absorption by the alkaline solution thus reducing substantially the amount of additional sulphuric acid required for the reaction.
