Developments in iron ore comminution and classification ...

2015-1-1  Future trends in iron ore comminution and classification 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.

Essay on Iron Ore : Nature, Classification and Production

2021-5-22  Essay # Classification of Iron Ore: According to usage, function-ability and composition, iron ores are principally of four major types: A. Magnetite (Fe 3 O 4): It is the richest among all iron ores with little impurities. The iron content varies between 70 to 72.5%. It contains magnetic properties, therefore it is suitable for electrical industries.

Effect of Mineral Density for Milling Magnetite Ores

There is a growing interest in magnetite ores because of the increasing demand for this commodity. With these ores, there is significant cost associated with milling the ore to fine sizes using ball mills in closed circuit with hydrocyclones. Cyclone classification efficiency tends to be poor due to the large difference in density between magnetite and gangue.
