Iron ore, coke and lime are added to the top of a furnace. Hot air is blown in from the bottom. The furnace operates at a high temperature (around 1200°C). Iron ore reacts with carbon/coke to form iron metal and carbon dioxide. The iron is tapped off at the bottom of the furnace.
A siliceous or metamorphosed banded ironstone, including iron-rich quartzites, interbedded jasper and iron oxides. They are usually banded mixtures of quartz and magnetite and/or hematite.They constitute many low grade iron ore deposits, collectively forming the largest accumulations of iron on the Earth (hundreds of megatons and more). Also a trade name for red, hematitized varieties of jasper.

Sep 01, 2017· The Mica Minerals. Andrew Alden. Phengite is a mica, K(Mg,Al) 2 (OH) 2 (Si,Al) 4 O 10, gradational between muscovite and the celadonite.This variety is mariposite. Phengite is a catchall name used mostly in microscopic studies for a mica mineral that departs from the ideal attributes of muscovite (specifically, a high α, β and γ and a low 2V).The formula allows considerable iron ...
Oct 05, 2016· 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 high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Though taconite was identified as an iron-bearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn't until then that it was profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing ...
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel.
