The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. Magnetizing roasting uses temperatures between 700 and 900 C for a time of under 1 hour to produce an iron concentrate (Fe 3 O 4) to be used for iron smelting.

Selective Flocculation Enhanced Magnetic Separation of. Simple magnetic separation for a certain magnetite mine with ultrafine disseminated lean ores has resulted in low performance as the fine sizes and aggregation of ground mineral particles have caused inefficient recovery of the ultrafine minerals In this study we attempt to increase the apparent sizes of target mineral

Stability ratios and flocculation rates computed from the model indicate that magnetic flocculation commences provided the total energy of interaction of particles is zero, and simultaneously the flocculation time is reasonably short. The latter condition increases the threshold magnetic field, particularly for large particles.
