Apr 28, 2022The reduction kinetics of copper slag by H2 are studied in this paper. The main phases of the copper slag were Fe2SiO4 and Fe3O4. The suitable conditions of reduction were a temperature of 1373.15 K, a H2 partial pressure of 40%, and a calcium oxide addition amount of 30%. In these conditions, the metal reduction ratio was 85.12%.

Heating and quenching rock can enhance liberation and increase mineral recovery in mineral processing. If the objective of size reduction is to liberate the valuable mineral component of an ore, then ideally fracture should follow intergranular paths, that is, grain boundaries. If so, the result would be liberation with minimum size reduction.
