Steel Slag an overview ScienceDirect Topics

Magnetic reseparation of the steel slag can improve the efficiency of intergrinding steel slag and OPC clinker by about 50% compared with intergrinding OPC clinker and nonmagnetically reseparated steel slag. The grindability of mixtures of steel slag and OPC clinker depends on the relative content and initial pregrind size of the steel slag.
