Making iron and steel from iron ore requires a long process of mining, crushing, separating, concentrating, mixing, agglomeration (sintering and pelletizing), and shipping to steel mills. Iron ore processing is characterized by a constant adaptation to changing raw materials and market conditions. It is the link between the mined
Composition: Hematite consists of iron (Fe) and oxygen (O) atoms, with two iron atoms bonded to three oxygen atoms in each formula unit (Fe2O3). Iron Content: Hematite is a rich source of iron, typically containing about 70% iron by weight. This high iron content makes it an important ore for iron extraction and steel production.

Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite is an iron oxide mineral. It is non-magnetic ...
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
