ABSTRACT:
Ores containing copper metal are reduced to the metal by mixing them with a carbonate catalyst, both being in the finely divided state, then mixing them with a chemical liquid solution comprised mainly of phosphoric acid, zinc oxide, and a sulfated surfactant which is in the concentrated state, or optionally water may be added, allowed to react chemically while stirring, then optionally boiled, then smelted at such temperatures as necessary to smelt (melt) the copper out of the mass (matrix).
