  • Copper in solidified copper smelter slags Jalkanen

    Copper losses in slag are of two main types: copper is either dissolved in molten slag as cuprous oxide (or as sulphide) or forms a mechanical dispersion in slag. For slag cleaning by froth flotation, mineralogy and morphology of solidified slag as well as chemical composition of copper‐bearing phases are of great interest.
