ABSTRACT:
A process suitable for recovering refractory metal carbide values from contaminated uncemented refractory metal carbides containing an iron group metal comprises heating an admixture of the powders of the contaminated refractory metal carbides and glacial acetic acid to the boiling point of the admixture for at least about 30 minutes, the weight of the powders divided by the weight of the acid is less than 5, thereafter removing the resulting carbide solids from the acid and washing the solids with sufficient water to remove the residual acid and drying the solids.
