  • Method of extracting germanium from germanium deposit using thermal reduction process
    Patent number: 10156003
    Abstract: A method of extracting germanium from a germanium deposit using a thermal reduction process is disclosed. The method includes: adding sodium monophosphate to a germanium deposit to obtain a mixed germanium deposit; isolating the mixed germanium deposit from air; increasing the temperature and then baking the mixed germanium deposit; and obtaining a germanium concentrate after volatilization of the mixed germanium deposit.
    Type: Grant

  • METHOD OF EXTRACTING GERMANIUM FROM GERMANIUM DEPOSIT USING THERMAL REDUCTION PROCESS
    Publication number: 20170121790
    Abstract: A method of extracting germanium from a germanium deposit using a thermal reduction process is disclosed. The present disclosure relates to a method of extracting germanium, which belongs to the field of metallurgy technologies of nonferrous metal, and particularly relates to a method of extracting germanium from a germanium deposit through thermal reduction, volatilization and concentration using sodium monophosphate as a reducing agent. The method of the present disclosure includes: adding sodium monophosphate to a germanium deposit; isolating from air; increasing the temperature and baking the germanium deposit; and obtaining a germanium concentrate after volatilization and concentration of the germanium deposit. Through baking the germanium deposit at 1,000° C., volatilization and concentration of the germanium deposit, the germanium recycling rate exceeds 96% when sodium monophosphate weighing 2.5% of the germanium depositis added.
