    US5492681A Method for producing copper oxide

    A method for producing copper oxide. In the method a copper bearing material aqueous ammonia and a sufficient amount of an ammonium salt to double the rate of production of copper oxide in the absence of the salt are placed in a single vessel. The vessel is closed and oxygen is fed into the vessel. The mixture is stirred and heated to a temperature of between approximately 70 and 130 C.
