Handling minerals in a slurry or suspension is preferable for many processors, especially when beneficiation involves wet processing. Additionally, a wet process often produces a …
Magnetic Separation Method
Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those ...

The process that is used for magnetic separation detaches non-magnetic material from those that are magnetic. Magnetic separation can be used in different environments and markets, so are magnetic separators used primarily for recovering metal from waste or purifying secondary materials by removing metals. But magnetic separators are also …
Electromagnetic Method
Electromagnetic separation is, however, a very expensive process, so that although its versatility justifies the operational costs for separating small quantities of a wide variety of isotopes, the process becomes prohibitively expensive for large quantities, say in excess of 10-100 grams depending on the element, the limit being even lower in ...
