[PDF]Get PriceThorium-232 is the most stable isotope of thorium and accounts for nearly all natural thorium, with the other five natural isotopes occurring only in traces. Thorium is estimated to be about three to four times more abundant than uranium in the Earth's crust, and is chiefly refined from monazite sands [ Monazite contains 2.5% thorium ...
Get PriceOnce you've got some thorium-rich Monazite sand, there's a straight-forward and well-known process for extracting high-purity thorium. You mix the sand with sulfuric acid, which gives a nice gray mud; wash that with cold water and treat with a couple more common chemical solutions, and boom your thorium precipitates right out as a nice sludge.
