Plasma-treated mineral sands (PTM) is mineral sands which have been passed through a high-temperature plasma which has made it more reactive. The unique properties of rare earth oxide allow for rapid dissolution using mineral acids. Tests are conducted on the three most popular acids, HCl, HNO3 and H2SO4 under dilute and highly concentrated conditions at various reaction temperatures. The results of rare earth oxide dissolution are presented with assumptions on the thorium and uranium dissolution.
