The paper presents the analysis of the state of art in the field of metallurgy of copper alloys. On the basis of the thermo gravimetrical measurements an original system, which modulates real conditions of reacting, was elaborated. Author shows on the most important role of the carbon {C~(2+)} and {C~(4+)} ions on the effectiveness of carbide slag metal extraction process In the presented work it has been decided to show the results of carbide slag investigated in the copper alloys industrial conduction. The paper presents the analysis of the ion reaction in to the slag during refining process and the problem of interfacial reaction between liquid slag and metal has been presented.
