When the iron ore is extracted from the 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.
Iron Mining Process. From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation’s steel. Blasting Taconite is a very hard rock. Using explosives the taconite is blasted into small pieces. The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings

Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite Fe 2 O 3 and magnetite Fe 3 O 4 . These iron ores have been mined to produce almost every iron and steel object that we use today - from paper clips to
Iron occurs naturally in the form of four stable isotopes: 54 Fe 56 Fe 57 Fe and 58 Fe. Around 92% of iron is 56 Fe. Oxidation States Iron can exist in oxidation states from -2 to 6. The most common states are 2 and 3. Interesting Facts about Iron. Cast iron is when an iron alloy is heated to liquid and then is poured into a mould.
Iron ores are minerals from which metallic iron can be extracted. The iron itself is usually found in the form of magnetite ? Fe 3 O 4 or hematite Fe 2 O 3 both of which are iron oxides.However as much of the pure magnetite and hematite ore has already been mined modern iron mines rely on aggregate minerals such as taconite ? which must be processed to remove non-iron-bearing components prior
