Iron Production. The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides.

Hematite has a wide variety of other uses, but their economic significance is very small compared to the importance of iron ore. The mineral is used to produce pigments, preparations for heavy media separation, radiation shielding, ballast, and many other products. Hematite's Streak: All specimens of hematite will produce a reddish streak.

Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things – nails, wire, car bodies, ship building, girders and bridges amongst others.

The ore-dressing process is also carried out to improve the chemical properties of ores by roasting, It means heating the substance strongly in the air to dry the ore, expelling humidity, converting the iron ore into oxide, increasing the ratio of iron in the ore, oxidation of some harmful impurities as (S and P). 2 FeCO 3 → 2 FeO + 2 CO 2

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

Figure 23.3.1 23.3. 1: A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged with alternating layers of iron ore (largely Fe2O3) and a mixture of coke (C) and limestone (CaCO3). Blasting hot air into the mixture from the bottom causes it to ignite, producing CO and raising the temperature of the lower part of …

The mixture of iron ore, coke, and limestone is known as charge. This charge travels on conveyor belts to the top of the blast furnace. The following illustration shows how conveyor belts are used to transport the charge mixture to the top of the blast furnace. These conveyor belts are run all day and night, and they constantly transport the ...
