Iron ore in the context of "Expropriation"

A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials/Intermediate goods that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products.

The term raw material denotes materials in unprocessed or minimally processed states such as raw latex, crude oil, cotton, coal, raw biomass, iron ore, plastic, air, logs, and water. The term secondary raw material denotes waste material which has been recycled and injected back into use as productive material.

The exploration of North America by Norsemen began in the late 10th century. Voyages from Iceland reached Greenland and founded colonies along its western coast. Norse settlements on Greenland lasted almost 500 years, and the population peaked at around 2,000–3,000 people. The colonies consisted mostly of farms along Greenland's scattered coastal fjords. Colonists relied heavily on hunting, especially of walruses and the harp seal. For lumber, they harvested driftwood, imported wood from Europe, and sailed to modern-day Canada.

Archaeological evidence indicates that the Greenland colonists used lumber and possibly iron ore imported from North America. Archaeologists found remains of one short-term settlement at L'Anse aux Meadows near the northern tip of Newfoundland. The remains of buildings excavated there in the 1960s dated to approximately 1,000 years ago. It was not a permanent settlement and lacked graves and livestock areas. The site was abandoned, seemingly deliberately, by 1145 AD with no valuables or tools left behind. Some wood fragments and nuts in the Norse remains were from plants not found in Newfoundland, but native to the continental mainland across the Gulf of St. Lawrence. No other settlements in Canada and no settlements on the North American mainland have been conclusively identified as Norse.

Magnitogorsk (Russian: Магнитого́рск, IPA: [məɡnʲɪtɐˈɡorsk], lit. '[city] of the magnetic mountain') is an industrial city in Chelyabinsk Oblast, Russia, on the eastern side of the extreme southern extent of the Ural Mountains by the Ural River. Its population is currently 410,594 (2021 census).

Magnitogorsk was named after Mount Magnitnaya, a geological anomaly that once consisted almost completely of iron ore, around 55% to 60% iron. It is the second-largest city in Russia that is not the administrative centre of any federal subject or district, after Tolyatti. Magnitogorsk contains the largest iron and steel works in the country: Magnitogorsk Iron and Steel Works. The official motto of the city is "the place where Europe and Asia meet", as the city straddles von Strahlenberg's line.

Esch-sur-Alzette (French pronunciation: [ɛʃ syʁ alzɛt], lit. 'Esch on Alzette'; Luxembourgish: Esch-Uelzecht [ˌæʒ ˈu̯əltsəɕt] ; German: Esch an der Alzette [ˈɛʃ ʔan deːɐ̯ ʔalˈzɛt] or Esch an der Alzig) is a university city in Luxembourg and the country's second-most populous commune, with a population of 37,922 inhabitants, as of 2025. It lies in the south-west of the country, on the border with France and in the valley of the Alzette, which flows through the city. The city is usually referred to as just Esch; however, the full name distinguishes it from the village and commune of Esch-sur-Sûre which lies 45 kilometres (28 miles) further north. The country's capital, Luxembourg City, is roughly 15 km (9.3 mi) to the north-east.

The town, first mentioned in the Middle Ages, remained a modest settlement for centuries until the discovery of iron ore in the 19th century transformed it into one of Luxembourg’s main industrial centres. The rapid expansion of mining and steel production attracted workers from across Europe, shaping Esch into a multicultural urban community. After the decline of the steel industry in the late 20th century, the city underwent structural change.

Iron is a chemical element; it has symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust. In its metallic state it was mainly deposited by meteorites.

Extracting usable metal from iron ores requires kilns or furnaces capable of reaching 1,500 °C (2,730 °F), about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechanical properties and low cost. The iron and steel industry is thus very important economically, and iron is the cheapest metal, with a price of a few dollars per kilogram or pound.

An iron oxide is a chemical compound composed of iron and oxygen. Several iron oxides are recognized. Often they are non-stoichiometric. Ferric oxyhydroxides are a related class of compounds, perhaps the best known of which is rust.

Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172.

Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores in the region from Greece to India, The use of wrought iron (worked iron) was known by the 1st millennium BC, and its spread defined the Iron Age. During the medieval period, smiths in Europe found a way of producing wrought iron from cast iron, in this context known as pig iron, using finery forges. All these processes required charcoal as fuel.

By the 4th century BC southern India had started exporting wootz steel, with a carbon content between pig iron and wrought iron, to ancient China, Africa, the Middle East, and Europe. Archaeological evidence of cast iron appears in 5th-century BC China. New methods of producing it by carburizing bars of iron in the cementation process were devised in the 17th century. During the Industrial Revolution, new methods of producing bar iron emerged, by substituting charcoal in favor of coke, and these were later applied to produce steel, ushering in a new era of greatly increased use of iron and steel that some contemporaries described as a new "Iron Age".

Tindouf, also written Tinduf (Arabic: ولاية تندوف), is the westernmost province of Algeria, having a population of 58,193 as of the 2008 census (not including the Sahrawi refugees at the Sahrawi refugee camps). Its population in reality could be as high as 160,000 because of the Sahrawi refugee camps. Despite the barren landscape, Tindouf is a resource-rich province, with important quantities of iron ore located in the Gara Djebilet area close to the border with Mauritania. Prior to Algerian independence, the area served as a strongpoint of several tribes of the nomadic Reguibat confederation.
