Relationships in flotation recovery of thorium-containing anions
The possibility of flotation recovery of thorium from solutions was first pointed out by Sebba. He also proposed a flotation method for the separation of thorium and uranium, based on the formation of anionic complexes by uranium at levels of solution pH at which thorium is still in the form of simple cations. Later, Shakir carried out a detailed investigation of the flotation recovery of thorium from dilute aqueous solutions by means of cetyltrimethylammonium bromide and lauryl sulfate, and Jacobelli-Turi in media.Sekine applied flotation in the concentration of thorium in the form of a complex with arsenazo III, for analytical purposes. In our previous studies, we had shown that it was possible in principle to recover thorium from dilute sulfuric acid solutions by flotation with aliphatic amines. Here we are reporting on further studies of this process. The materials we chose as thorium collectors in our studies were AAK and primary aliphatic amines (typical cationic surfactants); this type of surfactant was chosen because thorium in sulfuric acid solutions exists in the form of complex anions.
