Extracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy The steps need the ore to be concentrated first followed by the extraction of the metal from the concentrated ore after which the metal is purified
Iron Ore Formation Iron formation consists of iron ore such as siderite magnetite and hematite with silica in the form of chert jasper etc generally in bands but sometimes not distinctly so The bands of iron ore are at times highgrade but are often mixed with a good deal of silica the whole making an ore too lean for use without concentration
Iron ore is found in nature in the form of rocks mixed with other elements By means of various industrial processes incorporating cuttingedge technology iron ore is processed and then sold to steel companies The iron ore produced by Vale can be found in houses cars and household appliances
THE BLAST FURNACE IRON PRODUCTION Blast furnaces are used continuously and are only shut down when their brick lining needs replacing As the mixture of iron ore coke and limestone heats the hot waste gases are collected and cleansed They are then used to help heat the air blast required if blast furnace is to reach the high temperatures needed to produce molten iron
Iron mining in the United States produced 425 million metric tons of iron ore in 2015 worth US38 billion Iron ore was the thirdhighestvalue metal mined in the United States after gold and copper Iron ore was mined from nine active mines and three reclamation operations in Michigan Minnesota and of the iron ore was mined in northern Minnesotas Mesabi Range
Natural generation However almost all of the iron ore will be at the lower levels On average there are about 77 iron ores per chunk Veins can vary in size but the most common is 2×2×2 Iron always comes in veins of 4 to 10 unless dirt gravel a cave or another ore overlapped into it Each block in the vein which otherwise would be stone
