PROCESS FOR RECOVERING METAL VALUES UTILISING ORGANIC ORTHOPHOSPHATE EXTRACTANTS
Superior rssults in solvent extraction processes for recovery of metals, e.g., uranium, vanadium, etc., may be obtained by the use of a special class of organic orthophosphates as extractants. These orthophosphates are either mono- or mixtures of mono- and di-alkyl orthophosphoric acid esters with the organic substituents having from 9 to 17 carbon atoms. The preparation of such orthophosphates and their use for metal recovery from mineral acid solutions, aqueous slurries, nonaqueous slurries, and solid leaching processes are discussed in detail. Flowsheets, graphs, and examples are included illustrating each mode of metal recovery and uranium and vanadium recovery from leach solutions. The stripping of metal values from organic phases is also treated. (D.L.C.)
