Explain magnetic separation process of ores with the help ...

Magnetic separation process of ores: An electromagnetic separator is required. A leather or brass belt moves over two rollers, one of which encloses magnets in it. The powdered ore is dropped over this moving belt at one end. The non magnetic part of the ore is not attracted by the magnet and falls to form a separate heap at a distance.

Magnetic Separation - an overview | ScienceDirect Topics

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.
