    1), it can be concluded that the copper dissolved from the slag flotation tailings mainly originates from the copper oxide phases (about 10 wt.%), which are not amenable to flotation. Low copper extractions both from the slag and the slag flotation tailings indicate that sulphuric acid is not a suitable reagent for leaching these materials, at

    This work presents the study of copper extraction from smelter slag, which is subjected to sulphating. Sulphating of slag was performed by pyrite concentrate or flotation tailings at temperatures from 500 to 650°C, and the resulting calcine was leached with water. The results showed that maximum copper leaching (70-73%) is obtained from calcine, obtained by two and three hour sulphating at
