The optimum point of Titanomagnetite formation is shown at the time of iron sand reduction for 30 minutes with semi-quant level by 36%, so it could be understood the longer time reduction process of solid solution formation between ulvospinel and magnetite will be maximal. Addition of Na2CO3 to the alkaline roasting process followed by wuenching process using aquadest aims to remove impurities in the form of alumunium. Then the addition of Na2SO4 to reduction serves as a catalyst in the reduction process The authors also wish to thank the Ministry of Research Technology and Higher Education and Directorate of Research and Community Engagement, Universitas Indonesia, under PITTA Research Grants Contract No. 2459/UN2.R3.1/HKP05.00/2018 for the financial support of this research.

N2 - 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%.
