Principles of extraction of iron and its occurrences

An ore is that mineral in which a particular metal occurs in some significant amount and can be extracted economically. Some common examples of iron ore are hematite and limonite etc. Extraction of iron The extraction of iron is mainly from its oxide, i.e., hematite, and the process of extraction of iron involves the following steps.

Extraction of Iron - Online Math Learning

We can extract the iron by reacting the iron oxide with a more reactive element. The more reactive element takes away the oxygen. The raw materials are Haematite (iron ore), Coke (impure C), Limestone (CaCO 3) Make a strong reducing agent. C + O 2 → CO 2. CO 2 + C → 2CO. Reduce the iron 3. Fe 2 O 3 + 3CO → 2Fe + 3CO 2.

How to Extract Iron from Iron Ore - GulpMatrix

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.
