Iron ores include magnetite, hematite, limonite and siderite. These iron ores have different chemical compositions, mineral structures and physical properties, so their dressing process requirements are also different. In addition to these factors, factors such as the particle size distribution, hardness and embedded particle size of iron ore will also directly affect the …
