Document Type and Number:
Japanese Patent JPS6230130
Kind Code:
B2
Abstract:
Recovery of uranium from crude wet process phosphoric acid (WPA) by cation exchange using as cation exchanger a resin comprising active amino phosphonic or hydroxy phosphonic groups linked to a matrix. The operational steps comprise reduction of uranium in the WPA to the tetravalent state, contacting the WPAwith the cation exchange resin to load the latter with tetravalent uranium, displacing Fe+2 from the resin, washing the resin with aqueous ammonia, eluting the resin with a carbonate-bicarbonate solution and precipitating uranium from the eluate.
