Measurement and Characterisation of Metallic Iron …

 · Recent research showed that coal-based reduction followed by magnetic separation, which is a promising iron-making process, provides a feasible way of using refractory iron ores. In this process, iron oxides are reduced to metallic iron by coal, ground to obtain a liberation size, and subjected to magnetic separation to generate a good substitute steel scrap in electric arc furnaces …

Principles of Magnetic Separation

New models were developed for the classification centrifuge and the magnetic separator which could be used in a LIMN simulation of dense medium cyclone performance for a fines circuit. Models for DMC operating with fine coal hydrocyclones and sieve bends were developed from information in the literature.

Magnetic Separator

Conventional magnetic separators are largely confined to the separation or filtration of relatively large particles of strongly magnetic materials. They employ a single surface for separation or collection of magnetic particles. A variety of transport mechanisms are employed to carry the feed past the magnet and separate the magnetic products.
