أكمل القراءة· A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
أكمل القراءةObtaining metals from this ore is much easier. For example, Haematite ore ( Iron) and Bauxite ore (Aluminium) Sulphide Ores- In this particular ore, the metals are present in the sulphide form. Since it is difficult to extract metals from this ore, they are usually converted to oxides with the process of metallurgy.
أكمل القراءة· 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.

أكمل القراءة· Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the …
أكمل القراءةThe BOF process uses 30% of recycled steel, while EAF uses up to 90-. This is a far more sustainable option instead of mining more iron ore as a fresh ingredient in the steelmaking process. There is also an alternate steelmaking process called HIsarna ironmaking. In HIsarna, iron ore is processed immediately into hot metal.
