Types of Mining Magnetic Separators

Mining magnetic separator is common equipment in mineral processing. And magnetic separation is the main method of iron ore dressing. What minerals are required for magnetic separation? Common Iron Minerals are magnetite (strong magnetic minerals), hematite (weak magnetic minerals), Limonite, specularite, siderite (all weak magnetic minerals).
