Magnetic Separation Mining Fundamentals

Magnetic separation is the process by which magnetically susceptible material is separated from a mixture by the application of a strong magnetic field. Iron ores are usually subjected to the magnetic separation process, due to the high magnetic susceptibility of iron.

{The wet high intensity magnetic separation of magnesite

2019-11-15 · Magnetic separation is based on direct physical separation of minerals in a magnetic field. Related to magnetic properties, minerals can be divided into three basic groups: ferromagnetic, paramagnetic and diamagnetic. Due to magnetic susceptibility differences in particles the separation is accomplished wet or dry, at various magnetic field

Enrichment of Cobalt Values by Dry Magnetic Separation

2013-12-24 · All the classified fractions, excepting -75 µm size, were subjected to dry magnetic separation at different current intensities, viz. 10A (0.73 T), 15A (1.00 T) and 20A (1.23 T). The classified sample below 75 µm size was not processed through magnetic separator because of its low volume (7.5 wt.%) in the bulk sample.

Magnetic Separation an overview ScienceDirect

Carrier magnetic separation has been proposed for more effective separation of water and solids from acid mine water to generate very pure water (Feng et al., 2000).As discussed in Chapter 10, dissolved heavy metals like zinc and copper can be recovered from acid mine drainage (AMD) by selective precipitation controlling the pH for the precipitation of specific metals.
