6. Occurrence of Iron Iron is very reactive and is found in nature in form of its oxides, carbonates and sulphates. The main ores are: i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases. The process is continuous with raw materials being regularly charged to the top of the furnace and molten iron and slag being tapped fromPig Iron Production Blast Furnace Route Metallics

HIGH TEMPERATURE CHEMISTRY ROLE IN METAL PRODUCTION
The reduction and smelting of iron ore is done mainly in the iron blast furnace. The burden charged at the top of the furnace consists primarily of iron ore, flux and coke. The reducing gas carbon monoxide and the heat required for the smelting of the ore are generated at the bottom of the furnace by blowing preheated air into the coke bed.Extracting iron from iron ore using a Blast Furnace. Introduction. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat sourceiron and steel chemguide

Ironmaking 101 From Ore to Iron with Blast Furnaces
Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard First, the iron ore, the raw materials for steel, comes from the Earth. Most iron ores — hematite, magnetite, limonite — contain an average of 60% of iron (Fe). Before the iron ores enter a blast furnace, it undergoes ‘sintering’ which turns the pristine iron ore into more compact and appropriate sizes.Blast Furnace Anatomy #1 To the Heart of Steelworks Operation

Blast Furnace Reactions SpringerLink
In the blast furnace process, iron ore and reducing agents (i.e. coke) are transformed into hot metal and slag, which is formed from the gangue of the ore and the ash of coke. Hot metal and liquid slag do not mix due to their density difference and remain separate from each other with the slag floating on top of the heavier liquid iron.Blast furnaces have grown considerably in size during the twentieth century. In the early days of the twentieth century, blast furnaces had a hearth diameter of 4–5 m and were producing around 100,000 THM per year, mostly from lump ore and coke. At the end of the twentieth century the biggest blast furnaces had between 14 and 15 m in hearth Blast Furnace an overview ScienceDirect Topics
