Magnetic Separation Mine
Magnetic separation is generally a low cost method of recovery, unless high intensity separators are required. The electromagnetic high intensity separators that produce 20,000 gauss, tend to be expensive. However, the rare earth magnetic separators are relatively inexpensive and can produce magnetic fields around 6,000 gauss. So, when looking for a process to recover valuable minerals, .
