ABSTRACT:
A process for recovering copper from cupric ion containing aqueous solutions which comprises adding to the aqueous solution containing cupric ions an amount of reducing agent which corresponds from 0.1 to 10 moles of reducing agent per mole cupric ion, and heating the reaction mixture in the absence of oxygen in a closed vessel to a temperature of from 170.degree. to 240.degree. C., said reducing agent being one or more members of the group consisting of:
