METHOD OF SEPARATING RARE EARTHS BY ION EXCHANGE

Patent Spedding, F.H.; Powell, J.E.

A process is given for separating yttrium and rare earth values having atomic numbers of from 57 through 60 and 68 through 71 from an aqueous solution whose pH value can range from 1 to 9. All rare earths and yttrium are first adsorbed on a cation exchange resin, and they are then eluted with a solution of N-hydroxyethylethylenediaminetriacetic acid (HEDTA) in the order of decreasing atomic number, yttrium behaving like element 61; the effluents are collected in fractions. The HEDTA is recovered by elution with ammonia solution and the resin is regenerated with sulfuric acid. Rare earths are precipitatedmore »« less

PROCESS FOR SEPARATING RARE EARTHS AND YTTRIUM BY ION EXCHANGE

Patent Krumholz, P.; Lobo, R.M.E.; Bril, K.J.

A process for separating rare earths and yttrium by ion exchange is given which uses a second ion exchange bed ln the zinc or cadmium state rather than the copper state. The process comprises adsorbing the rare earth mixture on an lon exchange bed and eluting the bed with ethylenediamine tetraacetic acid through a second resin bed ln the zinc or cadmium form. The resin for both beds preferably is a sulfonated polystyrene--divinylbenzene copolymer of low crosslinkage (around 4%). Alternatively, a mixture of rare earths and a small amount of zinc or cadmium may be charged on one resin bedmore »« less
