Iron extraction and steelmaking - Chem Not Cheem

18/08/2020  8. Beyond the 3Rs: reworking the extraction of iron. Be that as it may, many countries depend on cheap steel to industrialise and uplift the poor. We cannot simply force them to reduce their steel consumption or use recycled steel that is more expensive. One way to have the cake and eat it is to change the way we reduce haematite to iron.

Extraction of Iron (examples, answers, activities ...

Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.

Iron ore extraction techniques - ScienceDirect

01/01/2015  As stated in the previous sections, the mining of iron ore, at both the surface and underground, ceased in the United Kingdom toward the end of the twentieth century, not only because of the general poor quality of the ores leading to high costs of production (from the deep mines) but also due to the environmental impact of surface mining, a problem that has dominated all attempts to mine minerals by opencast methods in the densely populated United Kingdom. Additionally, iron
