Treatment of copper refinery anode slime . United States Patent 4352786 . Abstract A process for the removal of lead content in anode slime by subjecting the latter to primary and secondary leach in a medium of an ammonium acetate solution at a temperature not exceeding 80 C. Whereby lead dissolution is maximized and other metals are ...

A Novel Process For Recovery Of Te And Se From Copper
Know More

In pressure oxidation leaching of copper anode slimes, more than 65 of the tellurium is co-extracted during decopperizing. About 10 15 of the selenium is also dissolved imultaneously by severe leach conditions. Current operation for the treatment of the leachate is to constantly recirculate the leach solution through a bed of copper turnings.
