How is iron extracted using a blast furnace?

11/05/2020 Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.

21/06/2018 A further lowering of the iron ores in the blast furnace leads to the temperature zone of 400 °C to 800 °C. In this region, the so-called indirect reduction of iron ores to iron by carbon monoxide takes place. The carbon monoxide gas (C O) is oxidized to carbon dioxide (C O 2) by absorbing the oxygen contained in the iron oxide (O).

How we make steel British Steel

Coke, iron ore, sinter and limestone are fed or charged into the top of the furnaces. A hot air blast of temperatures around 1,000°C is injected at the bottom of the furnace through nozzles called tuyeres. As the coke burns, temperatures higher than 2,000°C are reached and this heat creates molten metal (iron). The molten metal collects at the bottom of the furnace and the limestone

Blast Furnace Process. A blast furnace is a steel cylinder lined with refractory. It operates continuously until the lining wears out, which takes many years to occur. The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF. Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid iron ore

To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I.

The Making of Iron & Steel

The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent. The metallic iron produced by such a furnace contains a relatively high proportion of carbon (4%) and is passed to the steelmaking process as a liquid at approximately 1450C, called "hot metal".
