Abstract


Ilmenite is a natural material in the form of sand which contains heavy metal minerals that are very abundant in Lampung province. This research aims to determine the content of TiO2 from Lampungs iron sand by leaching method with temperature variation. The iron sand are mixed with sodium hydrogen carbonate (NaHCO3), then heated at 700◦C for an hour. This research uses 5 samples with leaching temperature variation of 70, 80, 90, 100, and 110◦C for 2 hours. The acid leaching process uses HCl 12 M with a ratio of iron sand and HCl of 1:4, while the water leaching process uses 50 ml of distilled water. Furthermore, the samples are characterized using XRD and XRF to determine TiO2 content in the iron sand. The result shows that the highest amount of TiO2 is obtained in the sample with the leaching temperature of 110◦C for 2 hours, which is approximately 61%.
