    The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore

  • 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.

    Some raw materials originate from conflict areas, where the conflict is funded by the extraction of raw materials. There is public opposition to such practices, so international agreements have been reached to derive these kinds of raw materials solely when the extraction has been guaranteed as “clean.” Many of the 17 metals that are processed in a cell phone originate from the African
