THE EFFECT OF REDUCTION TIME AND SIZE

THE EFFECT OF REDUCTION TIME AND SIZE

low-grade iron ore has the potential to be reduced by using a rotary kiln. A rotary kiln is a tool used to reduce low-grade iron ore and produce sponge iron with a high metallization. This process is in accordance with the Indonesian government policies that regulate the minimum value of percentage of sponge iron metallization for export, i.e. 85.
