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 WPA with the cation exchange resin to load the latter with tetravalent uranium, displacing Fe.sup.+2 from the resin, washing the resin with aqueous ammonia, eluting the resin with a carbonate-bicarbonate solution and precipitating uranium from the eluate.

Abstract: A spherical ion exchange resin composed of a phenolic resin and a metal hydroxide is disclosed. The metal hydroxide is enclosed and bound with the phenolic resin. A method for producing such an ion exchange resin and a method for selectively adsorbing ions using the same is also disclosed. The ion exchange resin is capable of efficiently recovering ions contained or dissolved in water in trace amounts and, hence, can be applied to any aqueous solution containing ions. For example, it can be used to recover useful substances from sea water and to purify waste waters from nonferrous refineries and nuclear power plants.

Abstract: A composition containing thiolate for the removal of heavy metal ions from dilute aqueous solutions, characterized in that the composition is a sorption complex of a thiolate with two or more -SMe- groups (wherein Me represents alkali or ammonium) with a swellable silicate, whose ion exchange capacity is 5-350 milliequivalents/100 g. The composition is suspended in the aqueous medium to be purified and separated off after the absorption of the heavy metal ions from the aqueous solution. The heavy metals can be recovered in known ways.
