Final answer:
The basic oxygen furnace is not used to produce pig iron, which is a false statement. The correct tool for pig iron production is a blast furnace.
Step-by-step explanation:
The statement that the basic oxygen furnace is used to produce pig iron is false. Instead, the basic oxygen furnace is primarily used in the process of steelmaking to convert molten iron into steel. Pig iron production occurs in a blast furnace. In the blast furnace, iron ore, typically hematite (Fe2O3) or magnetite (Fe3O4), is reduced by coke to form molten iron. This reduction process involves the blowing of air, which is heated up to 900 °C, through the mixture to turn carbon into carbon monoxide, facilitating the reduction of iron oxides to pure iron.
