Developments in iron ore comminution and

The in situ grade of magnetite ores is much lower (~ 20–50% Fe) compared with hematite/goethite ores. Therefore, magnetite ores will always require crushing and grinding followed by magnetic separation and, in some cases, reverse flotation to produce high-grade concentrates suitable for pelletizing.
