Thorium and rare earth recovery in Canada: the first 30 years

Canadian Metallurgical Quarterly, 2013
AbstractPioneering methods to recover thorium and rare earths as byproducts of uranium recovery were developed and applied in Elliot Lake, Ontario, during the 1960s. The district became a major supplier of these key elements from about 1960 until 1990 and at one stage supplied much of the world’s thorium and perhaps one third of its yttrium. This paper

Recovery of Thorium(IV) in Utilization of Solutions Formed in Sulfuric Acid Breakdown of Perovskite

Russian Journal of Applied Chemistry, 2004
Extraction of thorium(IV) with di-2-ethylhexyl hydrogen phosphate, octanol, and tributyl phosphate in sulfuric acid processing of perovskite was studied. The main stages of utilization of waste hydrochloric acid solutions were considered.

Anion-Exchange Recovery of Thorium from Uranium: Analytical and Preparation Aspects

Radiochemistry, 2003
Recovery of thorium from U(VI) containing 20% 235U in 7 M HCl with AV-17-8 chs anionexchanger [GOST (State Standard) 20301-74] was studied using a Ge-Li detector. An 1 cm column in diam-eter with 40-cm resin bed height ensures complete thorium separation from 1 g of U sorbed on the resin.
