Magnetite ore often occurs in metamorphic rocks, which formed from ferruginous sediments in both regional and contact metamorphic settings. It is commonly formed by the reduction of hematite and ferric hydroxide minerals in these rocks. Banded Precambrian iron formations commonly contain magnetite .
beneficiation of magnetite ore with some hematite. Iron Ore AIMR 2011 Australian Mines Atlas. The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4). highly magnetic, the latter property aiding in the beneficiation of magnetite ores. resulted in deferrals of ongoing exploration and development for some major iron ore
Magnetite beneficiation process flow: Magnetite beneficiation process equipment in magnetite ore dressing production line have their respective functions and duties. This series of equipment is mainly aimed at combining the weak magnetic separation and gravity separation, flotation, high intensity magnetic separation of hematite ore, ...
Hematite is often cheaper to process than other forms of iron ore as it generally does not require beneficiation due to its higher iron content. However, hematite ores may contain higher concentrations of contaminant elements (such as phosphorus, alumina and silica) and may therefore need to be blended prior to smelting.
