Iron ore, a type of coal called coke (which contains 85% carbon) and lime are added to the top of the blast furnace. ... The carbon and oxygen form carbon dioxide, and the lead is left behind as a metal. This is the same process that is used in iron extraction in the blast furnace, that we discussed above. Coke, which is mainly carbon, removes ...

Once iron ore is mined and extracted from the Earth's crust, ... while other alloying elements are added. This is the part of the process where steel emerges. We then cast, cool, and roll the steel for use in future projects. This process of heating, melting, and extracting metal from ore is called smelting. And while it is a highly ...

Ore is a deposit in Earth's crust of one or more valuable most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction. It is a common material in pipes and plumbing material.

Many metals can be reduced and extracted in a school laboratory. The easiest are iron, copper and lead. Over several lessons students can be taught how a metal is extracted and reduced from its ore. As you introduce each new example, increase the complexity of the chemistry. This process will continue during GCSE and Alevel studies.

Mild steel. Mild steel is iron containing up to about % of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others.

An ore is a type of rock containing compounds from which metals can be extracted. Ores are typically metal oxides or a compound of a metal that can be converted to an oxide. For example, the main aluminium ore is called bauxite which is aluminium oxide (Al 2 O 3). The metal is removed from the oxide in a process called reduction.
