Increased demand for concrete leads to an increase in utilization of cement and sand, and increased consumption of cement leads to increased CO2 emissions. Furthermore, mining restrictions in certain areas and the growing need for natural ecological sustainability lead to additional problems with river sand availability. This study promotes the utilization of …

Iron grain growth during deep reduction roasting is important for iron enrichment from copper slag (CS) through magnetic separation. In this work, a novel method of additive-free activation roasting, including oxidation and subsequent reduction roasting, was proposed to increase the iron grain size, then the iron was extracted by magnetic separation.
