  • SUSTAINABLE CONSTRUCTION

    Copper slag recycling and processing plant During blasting, copper slag breaks into smaller particles on impact with metal surfaces. After several rounds of reuse, the copper slag gets contaminated with rusts and paints and becomes a waste material but without any change in its chemical composition.

  • RARE EARTH ELEMENTS DISTRIBUTION KINETICS IN COPPER

    of REEs in copper matte slag systems is limited. The equilibrium distribution of REEs in a copper matte-slag system has been investigated but the study did not look at distribution kinetics [2]. At the moment REEs are not functionally recycled and more studies are needed on the possible avenues of recycling.
