FIELD: chemistry.
SUBSTANCE: at autoclave desorption, hot solutions of eluates are produced, and metal is further concentrated on carbon. Coal is continuously mixed during the process. Enriched eluate is divided into two parts, one of which is sent after cooling for the secondary concentration of metals, and the remainder without cooling is sent to the metal electrolysis with subsequent feeding into the continuous desorption apparatus. The technological line contains the installation of metal sorption from solutions and/or slurries, the installation of a secondary concentration of metals, in which a rich eluate supply is fed to an electrolytic metal separating unit, the installation of the metal desorption.
EFFECT: continuity of the technological process, increasing the concentration of noble metals, accelerating the electrolysis.
