 — ABSTRACT. Iron ore tailings dams at Quadrilátero Ferrífero, Minas Gerais (MG), Brazil, are full and present significant risks. The material contains approximately 30% of the iron, and recovering this iron is important in decreasing the environmental impact and increasing production.

High intensity magnetic separators focus on the separation of very fine particles that are para-magnetic. Controlled current is passed through an electromagnetic coil, which creates a magnetic field. This magnetises the yoke and finally the matrix ring. The separation matrix material behaves like a magnet and selectively attracts the magnetic ...
