Physical separation of iron ore: magnetic separation
Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron ores like martite, hematite, specularite, limonite, and siderite are weakly magnetic, and require high-intensity and high gradient magnetic ...
