This book was released on 1964 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thorium and yttrium oxides were recovered from siliceous ores of the Powderhorn, Colo., area.

About 95 pct of the contained thorium and yttrium was recovered from ore containing 1.2 pct ThO2 and 0.5 pct Y2O3. The thoria product was 99 pct ThO2 ; the yttria product was 77 pct Y2O3. A 150-to-1 concentration ratio was effected on the latter, but some contaminating lanthanon-group oxides remained.
