WebOct 7, 2024 · In this paper, graphite is used as a reducing agent to reduce Fe 3 O 4 in slag and reduce the viscosity of slag. It solves the problem that matte can not settle smoothly due to the high viscosity of copper slag, resulting in the high content of copper in slag. It provides a new way to recover matte from copper slag. iof retroativoWebThe results of the reduction rates of different carbonaceous materials in FeO-bearing slag showed that the reduction rates of fixed coke rods were slightly worse than those of graphite rods. This is mainly because coke contains a certain amount of ash that hinders the direct contact between slag and solid carbon as the reduction time increases. iof regulamento
