Abstract
A process for recovering uranium from a waste sludge involves treating the sludge with a non-reactive, non-absorptive cellulose filtration media, adding an oxidant and heating the mixture to dissolve any uranium present. The mixture is passed through a filtration device precoated with the same filtration media, where the solids are captured while the dissolved uranium passes through as part of the filtrate, for recovery.
