2014-9-11  During the pyrometallurgical process, the content of Cu strongly affects the composition of Au-Ag metal. Table II shows the copper content of silver/gold alloys after equilibration with pure oxygen.19 It is seen that at low gold content, the equilibrium copper content of Au-Cu alloys, independent of gold content, increased rapidly with a decreasing proportion of silver in the alloy.
