PENGOLAHAN PASIR BESI UNTUK MENINGKATKAN KADAR TITANIUM (Ti) DENGAN METODE PEMISAHAN MAGNETIK SECARA BASAH

Abstract

Iron sand is a type of sand that contains magnetite (Fe3O4). Iron sand is often found along the coast and has a shiny and black appearance. The presence of titanium content in ilmenite (FeTiO3) can provide significant added value to iron sand. In this study, the iron sand was sifted through 100 mesh for homogenization and the separation process was carried out by the wet magnetization method 4 times. The concentrate and tailings from the magnetic separation process in wet conditions with variations of 2, 4, 6, and 8 repetitions were then tested for XRF and SEM-EDS to determine the percent Ti and morphology. Optimal results of titanium enhancement were obtained under magnetic separation conditions in 4 repetitions with titanium morphology and dispersion. Separation of titanium by wet magnetic separation method can increase the titanium content from 3.05% by weight to 6.178% by weight and reduce the percentage of iron.
