Method for recovering solid molybdenum compounds.

摘要

Molybdenum can be removed from substantially anhydrous organic solution thereof by mixing the organic solution and an aqueous solution containing from 1 to 10 wt.% of dissolved sodium metaborate, the amount of aqueous solution being from 1 to 10 wt.%, based on the weight of organic solution, and being sufficient to provide a molar excess of sodium metaborate. The mixture is maintained at a temperature from ambient to 100 DEG C at a pressure of 0.1 to 7.0 MPa (0 to 1,000 psig) for 0.5 to 5 hours, thereby precipitating at least 95 mol% of the soluble molybdenum from the mixture, and providing a filtrate containing less than 100 ppm of molybdenum.
