Magnetic Separation - Mining Fundamentals

Magnetic separation takes advantage of the differences in magnetic properties of minerals. Most minerals fall into one of these categories: ferromagnetic, paramagnetic, and diamagnetic. Among these categories, ferromagnetic materials show the highest magnetic susceptibility, hence they can be easily separated by the magnetic separation method.

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to …

Magnetic susceptibilities of minerals - USGS

Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.
