Processes for extracting metal values from solutions |
| abstract |
A SOLUTION OF A METAL OR METALS IS CONTACTED WITH ENTITIES, E.G. IN A COLUMN, OF A HYDROUS METAL-CONTAINING GEL (MADE BY MIXING A SALT SOLUTION OR SOL OF THE METAL WITH A SOLUBLE POLYMER AND CONTACTING THE MIXTURE WITH A PRECIPITANT TO PRECIPITATE THE METAL OF THE SOLUTION OR SOL AS AN INSOLUBLE COMPOUND) WHICH SORBS ONE OR MORE OF THE METALS FROM THE SOLUTION. THE ENTITIES ARE SUBSEQUENTLY CONTACTED WITH A LIQUID WHICH DESORBS THE METAL FROM THE ENTITIES, SUITABLY A LIQUID WHICH DISSOLVES THE SORBED METAL. THE HYDROUS METAL-CONTAINING GEL SUITABLY CONTAINS THE METAL AS AN OXIDE, E.G. A FERRIC OXIDE GEL. THE PROCESS CAN BE REGARDED AS SOMEWHAT ANALOGOUS TO CHROMATOGRAPHIC ADSORPTION. IN ADDITION TO EXTRACTION, THE PROCESS CAN EFFECT SEPARATION, CONCENTRATION AND PURIFICATION. |
