Abstract: The problem of the sulfur-containing condensed products processing obtained during non-ferrous metals production are discussed. The results of thermodynamic and experimental investigations of sulfate sulfur transformations aimed at sodium sulfide and alkaline (NaOH) obtained are reduced. The conditions of sulfate sulfur in sulfide conversions, a high degree of conversion providing, as well as effective use of sodium sulfate as a main material for NaOH chemical obtaining in the system Na₂SO₄-C-CaO output Na₂O with providing, approaching at 100% are determinated.
