Abstract of the Disclosure Copper is recovered from solutions containing cupric ammoniacal complexes by reducing copper in the complexes to the cuprous state and thereafter precipitating the cop- per as cuprous acetylide by passing acetylene through the solution. After the cuprous acetylide is separated from the solution and washed thoroughly, it is reacted with ace- tonitrile and an acid to form acetylene and a cuprous- acetonitrile complex: Cu(CH3CN)?. The solution containing this complex is then flash distilled to remove the aceton- itrile and to disproportionate unstable cuprous ions into copper metal and cupric ions. Following the disproportion- ation, the components are separated and copper metal is col- lected.
