Which process is involved in the manufacturing of iron from iron-ore?

The process involved in the manufacturing of iron from iron ore is Reduction.

Iron ore is mainly composed of iron oxides, primarily hematite (Fe2O3) and magnetite (Fe3O4). The iron in the ore is extracted by a process called reduction. In this process, oxygen is removed from the iron oxides to produce elemental iron, which is then further processed into steel or cast iron. The reduction of iron ore can be achieved through several methods, including direct reduction and blast furnace processes.

The most common method is through the use of a blast furnace, where iron ore, coke (carbon), and limestone are fed into the top of the furnace, and hot air is blown into the bottom. The coke serves as both a fuel and a reducing agent, reducing the iron ore to iron.

Therefore, the correct process involved in the manufacturing of iron from iron ore is reduction.
