Processing Of Magnetite Iron Ores

Dec 31, 2018 Mining and processing hematite and magnetite ores. High-grade hematite ore is referred to as direct shipping ore (DSO) as, once mined, the ore goes through a simple crushing and screening process before being exported for steel-making. Australia's hematite DSO from the Hamersley province averages from 56 to 62 Fe.Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Beneficiation Of Iron Ore Process Why With Magnetite

Crude ores in which most of the recoverable iron is magnetite (or, in rare cases, maghemite) are normally concentrated by magnetic separation. The crude ore may contain 30 to 35 percent total iron by assay, but theoretically only about 75 percent of this is recoverable magnetite. The remaining iron is discarded with the gangue.Jul 10, 2017 The black sand magnetite is a raw material to produce iron and steel. High content magnetite in the top meter beach sands of the north-west of El-Burullus Lake of Egypt is separated and mineralogically and geochemically investigated.
