Indonesia has great iron mineral resources, comprising primary iron ore (17 %), iron sand (8 %) and lateritic iron ore (75 %). Nowadays, Indonesia's primary iron (hematite, magnetite) has not been em- powered yet, due to the scattered area of the resources location. Meanwhile, national iron sand is commonly used for cement industries and its …
