ABSTRACT:
The present invention relates to a special process for the recovery of molybdenum by the wet-chemical digestion of molybdenum sulphide containing materials by means of nitric acid. The invention relates especially to the combination of a leaching procedure (that provides a very pure molybdenum oxide) and a liquid extraction procedure for the recovery of molybdenum and other values from the residual solution that is left over from the leaching procedure.
