“…In general, minerals that do not respond to magnetic fields are called non-magnetic minerals consisting of quartz, mica, corundum, gypsum, zircon, and feldspar. Meanwhile, minerals that respond to magnetic fields are magnetic minerals containing the Fe element, such as magnetite, hematite, ilmenite, and siderite [8][9][10]. Therefore, the objectives of the present study are to synthesize MIL-100(Fe)@Fe3O4 composite using zircon mining magnetic waste and to clarify its ability as an adsorbent for methylene blue dye.…”
