Abstract

This study aims to determine the effect of sodium sulfate (Na 2 SO 4 ) addition on the reduction proses of tiania iron sand. The sample that used in this research are the iron sand that taken from Sukabumi, West Java, coal as reductor, sodium carbonate (Na 2 CO 3 ), and sodium sulfate (Na 2 SO 4 ) as additive and primary parameter. From the result of XRD characterization and semi-quantitative analysis the addition of sodium carbonate (Na 2 CO 3 ) on roasting process remove the impurities like alumuniom oxide (Al 2 O 3 ). In the other hand, the content of titano-magnetite (Fe 2 TiO 4 -Fe 3 O 4 ) in the iron sand increase with addition of sodium sulfate (Na 2 SO 4 ). Meanwhile, from semi-quantitative analysis result with the variation of sodium sulfate (Na 2 SO 4 ) in 5%, 15%, and 25% have an optimum point on the addition of 15% sodium sulfate (Na 2 SO 4 ) with 46,9% of titano-magnetite (Fe 2 TiO 4 -Fe 3 O 4 ) content.
