Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world''s iron and steel industries.

The biggest source of iron on the planet comes from banded iron formations Bandadas (FFB), known in Brazil as itabirites and jaspelitos. These rocks, after many intense physical and chemical processes, promote the removal of silica, turning the rock into hematitite. It is the greater or lesser presence of hematite in ore, which determines the iron content of a deposit.

Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species

Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.

Iron ore are rocks from which metallic iron is extracted – this has been used for over 3,000 years. Of all the iron ore extracted across the world, 98% is used to make steel. Steel is widely used for building different structures in our modern world, from buildings, bridges, cars and trains to pipes, bolts, nails and our machinery. Ukraine is the sixth largest

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

US iron mining is most prevalent in Minnesota and Michigan. The majority of the mining found for these operations is Surface Mining. This form of mining is when minerals are directly removed from the ground surface area. It is also commonly known as "open cast mining", making up the majority of metal ore mining. More than 95% of all nonmetallic minerals involved this type of mining.
