Separation of thorium from uranium ore SpringerLink
Thorium230 has many research applications, but there is not a commercial source of this isotope However, since 230Th is part of the 238U decay chain, it can be separated from naturally occurring uranium In this work, a novel procedure was developed to separate thorium from uranium ore, consisting of leaching, liquid–liquid extraction, precipitations and ion exchange chromatography The removal of radioactive elements thorium and uranium from the leach solution of ionadsorption rare earth ores by aluminum sulfate was studied using di(2ethylhexyl) [N(2ethylhexyl)aminomethyl] phosphonate (Cextrant 230, L)The extraction of thorium, uranium, rare earths, aluminum and other elements was investigated in detail, especially for uraniumRemoval of thorium and uranium from leach solutions of ion Hydrometallurgical removal of uranium and thorium from Ethiopian tantalite ore Mulugeta Sisay Cheru 1, Alberto Velázquez del Rosario 2, 90% wt/wt) was used for the leaching of uranium and thorium at an ore to acid ratio of 1:6 wt/wt The leaching step was conducted in the presence of oxygen, which was introduced by blowing oxygen into the beaker, to facilitate the oxidation and Hydrometallurgical removal of uranium and thorium from
(PDF) Hydrometallurgical removal of uranium and thorium
The leaching and extraction behavior of uranium and thorium from a highgrade Ethiopian pegmatite ore in a mixture of hydrofluoric acid and sulfuric acid has been investigated The effects of At Elliot Lake, Ontario, thorium has been recovered from uranium ore leach solutions, after removal of the uranium by ion exchange resin, since 1959 A solvent extraction process is used, and the thorium is recovered as thorium sulfate by stripping the loaded solvent with moderately strong sulfuric acid The product, recovered by filtration, is directly shippable, but can also be easily Recovery of thorium from uranium solutions NASA/ADS Thorium, as a nuclearpower replacement for the uraniumbased nuclear reactors and an effective avenue to produce uranium source, has become a key element for the increasing energy demand However, we now are seriously restricted to gain thorium from mineral, due to coexistence of thorium, uranium, and rare earth elements Accordingly, there is an urgent need to develop solid Selective extraction of thorium from uranium and rare

Recent progress in impurity removal during rare earth
412 Behaviour of thorium and uranium Thorium and uranium are known to associate with REE mineralization and are usually present in most commercial REE ore materials The usual approach to impurity removal by solvent extraction is to perform a separate solvent extraction step specifically engineered to selectively extract thorium or uranium One approach to recovering the thorium is through various stripping, filtration, separation, and calcining steps In this process, thorium is considered a nuclear fuel due to its fertility and relative abundance compared to uranium Thorium can accept a neutron and transmute to uranium223, which can then undergo nuclear fission to produce fuelExtraction of Thorium Oxide from Monazite OreUranium mining is the process of extraction of uranium ore from the ground The worldwide production of uranium in 2019 amounted to 53,656 tonnes Kazakhstan, Canada, and Australia were the top three producers and together account for 68% of world uranium production Other important uranium producing countries in excess of 1,000 tonnes per year were Namibia, Niger, Russia, Uzbekistan and Uranium mining Wikipedia
