The densities of molten copper mattes Cu2S-FeS, Cu2S-ZnS and FeS-ZnS were measured in the temperature interval 1, 150°C to 1, 370°C, using “U-tube method” with W-probe. Several density values were also obtained for the ternary matte Cu2S-ZnS-FeS in the same temperature range.
The densities of binary mattes Cu2S-FeS, Cu2S-ZnS and FeS-ZnS, and that of ternary matte Cu2S-ZnSFeS were measured as 5.70-3.77g/cc, 5.70-4.11g/cc, 3.99-3.33g/cc, and 5.25-3.91g/cc, respectively. Molar volumes and partial molar volumes of the binary mattes were evaluated.
