ABSTRACT:
A process for re-extracting trivalent iron and hexavalent molybdenum from an organic phase containing an organophosphoric compound.
In a first step the organic phase is contacted with such a quantity of water that most of the iron and only a minor part of the molybdenum are re-extracted.
In a second step the partially unloaded organic phase is contacted with such a quantity of water that most of the molybdenum contained therein is re-extracted.
This two-step re-extraction process permits obtaining a high reextraction yield for both molybdenum and iron, while ensuring the production of a concentrated eluate.
