magnetic induction. As the separation force is proportional to a field and a field gradient, then 10 Tesla systems offer unrivalled performance. Thus, it can be concluded, that 10 Tesla = high throughput = the highest available separation force. Separation of Kaolin Clay Kaolin is a naturally occurring white clay consisting of
Kaolin is a clay mineral that has a wide application in the industry, depending on its purity. ... The amenability of using magnetic separation for removing the iron oxide and titanium oxide ...
In mineral processing, conventional magnetic separators are equipped with traditional magnetic circuits (magnetic iron yoke with copper coils or iron-clad solenoid) that develop magnetic fields of less than 2 T*. For minerals of low magnetic susceptibility, use of these circuits has many disadvantages. Only a separator with a superconducting magnet can …
