Abstract

Indonesia has rich deposit of Iron Sand that can be found along of the Java southern part island. Iron sand contains some Ti-Rich minerals such as ilmenite, titanomagnetite dan rutile. This study aims to determine the effect of time variation on the results of Increasing titanomagnetite in iron sand and addition of 15% Na 2 SO 4 as a catalyst. Variation of this reasearch was respectively 10 minutes, 20 minutes and 30 minutes with reduction temperature at 800°C. It takes the stage of roasting to condition the ore to be more easily reduced and increase the metal content so that it can maximize the iron sand purity with addition of Na 2 CO 3 additive with mass ratio 1:0.4. Based on the XRD and Semi-Quant equation using Software HighScore Plus, optimal time for reducing iron sand with coal at 800°C is 30 minutes, which produce content of titanomagnetite as much as 36%.
