Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).
Used earlier by the iron and steel industry, limonite and other East Texas iron ores have more recently been mined for use in preparing portland cement, as a weighing agent in well-drilling fluids, and in animal-feed supplements. When iron production virtually ceased in 1910, less than 700,000 long tons of ore had been processed.
The Iron Age began around 1200 BC, ending the Bronze Age that preceded it and paving the way to man's mastery of metal. Individuals during this period began extracting iron ore to forge tools and weapons. The reason revolves around Iron being one of the most abundant metals found on earth. Iron makes up 98% of earth's core and 5% of earth's crust.

The principle ores of iron are Hematite, (70% iron) and Magnetite, (72% iron). Taconite is a low-grade iron ore, containing up to 30% Magnetite and Hematite. Shipment / Storage The carriage of most iron ore products in bulk form is subject to the provisions of the International Maritime Solid Bulk Cargoes Code (IMSBC-Code).
Mining iron ore typically involves finding a fertile site, drilling and blasting the ore, and then transporting it to the primary crusher for processing. Crushed ore is sorted over screens and resized to different specifications (lump and refined products). After the processing, a stacker builds a stockpile in the stockyards.
WA Iron Ore reaches autonomous drilling milestone 02 June 2022 BHP WA Iron Ore has reached a significant milestone, with our drills operating autonomously for more than 479,607 hours, drilling more than 25 million metres. That is equivalent to drilling the distance from Perth to Newman almost 21 times!
Significant intercepts from the company's latest probe include 11m at 57.3 per cent iron from 34m, 12m running 57.2 per cent from surface, 11m going 57.1m from 33m, 16m grading 57 per cent from surface and 11m at 57 per cent from a depth of just 35m.

In 2016-17, the volume of iron ore sales reached a record 790 million tonnes and was valued at $63.6 billion. Uses Iron is the world's most commonly used metal, and iron ore is a key ingredient for steel making. To produce 1,000 kilograms of crude steel requires about 1,400 kilograms of iron ore (and around 800 kilograms of coal).
FMG close to drilling new iron ore project FORTESCUE Metals Group founder and chairman Dr Andrew Forrest says the company will start drilling at the Belinga iron ore project in Gabon in early 2023. Exploration / Development > Events-coverage 24 November 2022
Magnetite. Limonite. Siderite. The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.
Ore is identified by diamond drilling core samples on a grid several meters into the earth. iron ore rock comprises a substantial percent of iron and the rest is impurities such as …
Kumba's all-women drilling team take iron ore firm's future forward, bit-by-bit. IN early 2018, JSE-listed Kumba Iron Ore announced it was considering a 'step out' strategy having in the previous year restructured its Sishen mine in the Northern Cape, a move that cut the operation's life to 13 years from 17 years previously.
Conducted across a 220km² area in the central region of the Mayoko project area, the survey revealed six drill targets covering 0.7t to one billion tons of iron ore. A similar survey conducted on the remaining 780km² in 2010 increased the exploration target to 1.6-2.6 billion tonnes of ore graded at 30%-65% Fe.
In the Lake Superior iron-ore districts a combination diamond- and churn-drill machine, known as the Mesabi rig, has been used extensively. When drilling is done in soft formations that will break and thus not return a core, vertical holes may be drilled with a chopping bit screwed on the end of the regular string of rods.
The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.

The drillers have to tackle three main ore types; laminated iron ore, drilled at 120 –130 m per shift (using the PV-271 and single-pass DTH drilling), loose conglomerate, and compact conglomerate. Very abrasive phyllites and quartzites are also encountered as well as "soft" iron on the Mokaning development property.

Blasting in iron ore is done by putting explosives materials which are drilled into holes and fired to break and loosen intact rock, so that ore and other material can be excavated and delivered to the processing plant, a stockpile, or a waste dump.
Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock.
