The reactions of TiS2, VS, Cr2S3, MnS, FeS, CoS, NiS, CuS and ZnS with molten potassium nitrate were studied. In the melt, Ti, Ni, Cu and Zn metal cations exhibited acid-base reactions and were precipitated as metal oxides whereas V, Cr, Mn, Fe and Co metal cations showed oxidation-reduction as well as acid-base reactions and were converted into VO3-, CrO42-, MnO2, Fe2O3 and Co3O4 respectively. The sulphide sulphur in all cases was oxidized to sulphate and the nitrate melt was reduced to nitrite and oxides of nitrogen. The stoichiometries of these reactions have been established.
