(IRON ORES) The magnetic separation method is used when either the ore or the gangue particles are magnetic in nature.
Among the ores listed,the iron ores are magnetic.
Specifically,$Haematite (Fe_{2}O_{3})$,$Magnetite (Fe_{3}O_{4})$,$Siderite (FeCO_{3})$,and $Iron pyrites (FeS_{2})$ are iron-containing ores that exhibit magnetic properties and can be concentrated using this method.
