ABSTRACT:
The solid organic materials contained in wet-process phosphoric acid are removed by froth flotation in a flotation cell in which the solid organic materials overflow with the foam from the top of the cell and the acid, after passing through the cell, is passed to extraction. The froth flotation process can also be used to remove defoamer and organic soluble materials from the wet-process phosphoric acid. Uranium in the partially purified phosphoric acid product is extracted with a suitable organic extractant, typically a mixture of mono- and di-(alkylphenyl) esters of orthophosphoric acid.
