  • Salt-soda sinter process for recovering aluminum from fly ash
    Patent number: 4254088
    Abstract: A method for recovering aluminum values from fly ash comprises sintering the fly ash with a mixture of NaCl and Na.sub.2 CO.sub.3 to a temperature in the range 700.degree.-900.degree. C. for a period of time sufficient to convert greater than 90% of the aluminum content of the fly ash into an acid-soluble fraction and then contacting the thus-treated fraction with an aqueous solution of nitric or sulfuric acid to effect dissolution of aluminum and other metal values in said solution.
    Type: Grant
    Filed: March 27, 1979
    Date of Patent: March 3, 1981
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: William J. McDowell, Forest G. Seeley
  • Recovery of aluminum and other metal values from fly ash
    Patent number: 4252777
    Abstract: The invention described herein relates to a method for improving the acid leachability of aluminum and other metal values found in fly ash which comprises sintering the fly ash, prior to acid leaching, with a calcium sulfate-containing composition at a temperature at which the calcium sulfate is retained in said composition during sintering and for a time sufficient to quantitatively convert the aluminum in said fly ash into an acid-leachable form.
