The chemistry of steelmaking. The big picture.

The chemistry of steelmaking. The big picture.

+

This is why we do not find pure iron in the Earth's crust. Instead it is found as an ore, in which iron is chemically combined with oxygen or other nonmetals. Most workable iron ores are rich in iron (III) oxide, Fe2O3. Making iron by removing oxygen from the ore is the first step in the manufacture of steel. Reduction and oxidation.

 · 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 into it from beneath via small pipes known as tuyeres.

Direct reduced iron process

 · Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the socalled direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

 · An estimated 340 million tonnes of iron ore were produced in China in 2020, placing it third on the list of the largest iron ore producing countries. China is also the world's biggest consumer of the commodity, and combines domestic production with additional foreign imports to feed its huge steelmaking industry, which currently accounts for more than half of the world's steel output.

Several processes based upon the direct reaction of coal and iron ore in a rotary kiln, such as the SL/RN process, have reached various stages of development since the 1960s. 20 Due to the high gangue and low specific productivity of these processes, they have not received a great deal of attention for commercial production.

Extraction of Iron Concentration of Ore

Extraction of Iron Concentration of Ore

+

 · Concentration of Ore. The extraction of iron begins with concentration through calcination which is a process in a limited supply of oxygen applied to ores to bring thermal decomposition. An ore of a metal is an impure source. It consists of many impurities other than metal such as sand, clay, etc.

 · A precondition for the geographical concentration of the iron and steel industry at the end of the 19th century was the development of communiions – particularly the railways. Steelworks demanded a cheap supply of materials – coal, ore, etc. – as well as good transportation facilities to the export harbours for the finished steel.
