how to process thorium

US3146063A for separating scandium from

1 the process for separating scandium from a mixture of scandium and thorium which comprises precipitating the thorium as the insoluble iodate from a mineral acid solution containing ions of scandium and thorium by adding a soluble iodate ion in aqueous solution said mineral acid being free of ions which would prevent the iodate

Thorium Production

Thorium is extracted from its phosphate contained in monazite concentrates Two industrial ways of processing are commercially significant Treatment by sulphuric acid at 200°C sulphatization Treatment by alkaline at 140°C

Monazite

Thorium content of monazite is variable and sometimes can be up to 20 30% The final products yielded for this process are thorium phosphate concentrate

What is Thorium

How is Thorium extracted Thorium has been extracted primarily from monazite through a complex multi stage The monazite sand is dissolved in hot concentrated sulfuric acid H2SO4
