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 uraniumWashing the tantalite concentrates using 1vol% KOH and 1 M H2SO4 led to the removal of thorium and uranium radioactive oxides from the concentrate out on a lowgrade uranium ore with emphasis (PDF) Hydrometallurgical removal of uranium and 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 chromatographySeparation of thorium from uranium ore SpringerLink

Laserinduced breakdown spectroscopy
Laserinduced breakdown spectroscopy (LIBS) was used to analyze depleted uranium and thorium oxide powders and uranium ore as a potential rapid in situ analysis technique in nuclear production facilities, environmental sampling, and infield forensic applications Material such as pressed pellets and metals, has been extensively studied using LIBS due to the high density of the material and Uranium 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
