Iron ore - Wikipedia

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.

Iron Ore - an overview | ScienceDirect Topics

Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm. The crushed product is screened in two stages. The overflow of the first screen (+40 mm) is recrushed.
