With the object of knowing the behavior of molten copper sulphide at high temperatures, the equilibria of H_2S/H_2 gas mixtures with the melts from compositions corresponding the two-liquid range to compositions close over cuprous sulphide in Cu-S system were measured by a flow method at temperatures of 1,135°, 1,185° and 1,230℃, as a part of fundamental investigations in chemical reactions in the converting of copper matte. The results obtained for the melts in two-liquid range are represented by the following equation : [chemical formala] Combining this equation with the one of hydrogen sulphide gas, the corresponding equation for the sulphur pressure of this range will be as follows : [numerical formula] Basing on the results measured, some related thermodynamic quantities were calculated and a study was made on the portion of Cu-S equilibrium phase diagram taking part in the melt.
