ESTIMATED MANUFACTURING COSTS FOR THE RECOVERY OF THORIUM AND URANIUM FROM MONAZITE SAND [PDF]

, 1950
Costs are estimated for the production of uranium and pure thorium from monazite concentrates. The process involves; reaction of the monazite with caustic soda, dissolution of the hydrous oxides in hydrochloric acid, separation from the bulk of the rare earths by hydroxide precipitation of thorium and uranium, and purification by solvent extraction ...
