A solution of yttrium and rare earth chelates of ethylenediaminetetraacetic acid was prepared by mixing a hydrochloric acid solution of Lindsay yttrium concentrate with the requisite quantity of 0.5% ethylenediaminetetraacetic acid solution, adjusting to pH 7.5, and losing on coppered columns. Some rare earth leakage was noted due to high pH. Loading was continued until two columns were filled with rare earths, and the rare earths were then eluted through two more columns. Of the total rare earths recovered, no high purity or 99.9% yttrium oxide was produced; 26.9% was 99% yttrium oxide and 15.9% was 95% yttrium oxide. The separation of the small amounts of other rare earths from the yttrium still required two band lengths. (auth)
