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 700⁰ C for an hour. This research uses 5 samples with leaching temperature variation of 70, 80, 90, 100, and 110⁰ 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 110⁰ C for 2 hours, which is approximately 61%.
