  • Thorium Extraction Methods - UC Homepages

    when thorium-232 absorbs a neutron, it transmutes to uranium-238, a viable nuclear fuel. Originally, thorium extraction was a process that was high in energy and waste, using large amounts of heat and solvent. Modern science is working to produce thorium more efficiently. In this paper, several common thorium extraction processes are discussed.

  • Measuring thorium and potassium levels in sand

    A. The relative amounts of potassium and thorium in beach sand can vary quite a lot. Typical potassium levels are 1% to 2% by weight (10,000­20,000 ppm), but values less than 1% and greater than 3% have frequently been observed. Thorium levels may also vary significantly. Values from 5 to 15 ppm by weight are common for ordinary beach sand.
