flow chart of limestone ore process
While limestone may seem unrelated to the production of iron and steel, it actually is an essential auxiliary material that is added during the production process. During the process of reducing iron ore, it is necessary to remove the silica, alumina (Al 2 O 3 ), and other non-ferrous components contained in iron ore.

Raw materials. For the production of steel, there is a need for iron raw material in the form of iron ore or scrap metal, together with alloying elements so that the material acquires the desired for properties. In the production of ore-based steel, coal is also needed as a reducing agent and limestone as a slag former.

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron (III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced

Answer: Usually, limestone (calcium carbonate, CaCO3) is “calcined" in a lime kiln, where it is heated to form lime (CaO) and CO2 gas. The lime is then used in both steelmaking furnaces to refine liquid iron into steel, and also on ladles as slag to further refine the steel.

Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as 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 (Fe3O4) and hematite (Fe2O3). It’s a major ingredient in steel.

They are (i) raw limestone products, (ii) calcined limestone or quicklime products, and (iii) hydrated lime products. The processing for limestone for these products is described below. The first process takes place at limestone mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore.

Coke, limestone flux, and iron ore (iron oxide) are charged into the top of the furnace in a precise filling order which helps control gas flow and the chemical reactions inside the furnace. Four "uptakes" allow the hot, dirty gas high in carbon monoxide content to exit the furnace throat, while "bleeder valves" protect the top of the furnace from sudden gas pressure surges.
