“…Iron sand is a magnetic material that has the properties of a ferromagnetic material (Gunanto et al, 2018;Karbeka et al, 2021;Yulia and Erwin, 2019). Iron sand has several mineral contents such as hematite (𝛼-Fe 2 O 3 ), maghemite (𝛾-Fe 2 O 3 ), ilmenite (FeTiO 3 ), silica (SiO 2 ), magnetite (Fe 3 O 4 ), alumina (Al 2 O 3 ) and rutile (TiO 2 ) (Nengsi et al, 2016;Sihombing and Amiruddin, 2020;Susilawati et al, 2019). In addition, many unnecessary minerals (gangue) such as K, C, Mg, Na, Si, Al and Ca elements attached to iron ore can reduce the magnetic properties of iron sand.…”
