Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a
The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.
Iron ore mining techniques differ by the type of ore that is being hauled out. There are 4 types of iron ore deposits that is being worked on at present, Based on the mineralogy and geology of the ore deposits.
The rock is mixed with water and ground in rotating mills until it is as fine as powder.
Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.
Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)·n(H2O)) or siderite (FeCO3). Roughly 98% of iron ore on the global market is used in iron and steel production. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iro
1/1/2015· The deep mining of iron ore is unusual in the modern era, but in northern Sweden, ore is mined from considerable depth largely aided by the application of automation and remote control equipment. Kiruna has been chosen as the example for a more detailed review of
Currently most of the iron ore mined in the world comes from large deposits of massive hematite rock formed by the in situ enrichment of a protore already enriched in iron, most commonly a banded iron
Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be

Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic
The process of mining of iron ore from discovery of an iron ore deposit body through extraction of iron ores and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the iron ore deposit, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
Iron Mining Process Map Environment News Media Links 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
This saves mining operations multiple millions in USD every month since iron ore beneficiation increases significantly the costs per ton of ore. Control of the moisture content on the mining conveyor belt (NIR) together with accurate monitoring of the composition of iron ore before shipment guaranties constant ore quality to avoids penalties.
Iron metal may be produced from the smelting of certain iron compounds. Their concentration in economic proportions is referred to as 'iron ore'. Other well known uses of iron compounds are: Iron sulfate used as fungicide, the oxalate of iron in photographic
The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is

Smarter steels depend on high-quality raw materials. As one of the world’s leading producers of iron ore, we supply nearly half of our own iron ore needs and provide the types of coal that are essential to steelmaking. Our mining assets provide supply security and quality for our own operations, and a source of high-value raw materials for our customers.
