Processes and Procedures in the Extraction of Iron ...

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.

What is Smelting?, and Iron ore Smelting process ...

13/09/2019  Iron smelting involves two main processes in the blast furnace: (1) the reduction of iron from it compounds and (2) its separation from its physical mixture with gangue materials. In furnace, the charge is constantly moving slowing downward against the force flow of the very hot gases which bring about the evaporation of moisture from the charge at the top.

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 ...
