     Kaolinite-pyrite cinder was separated iron ore concentrate with Fe grade of 57.5% and tailings mainly containing metakoalin using magnetic separation after magnetizing roasting. The results show that the tailings can significantly reduce the heat of hydration of cement and react with Ca(OH)₂, improving the microscopic structure of the cement paste for microstructure more homogeneous dense in the late of hydration cement paste. The water requirement of normal consistency and setting time increased when containing tailings in the cement paste.
