treatment with acids
oxidation
blast reduction
treatment with alkanal
Explicación
Blast furnaces are the first step in the modern process of manufacturing steel from iron ore:
- Blast furnace: Iron ore, coke, and limestone are used to produce pig iron in a blast furnace.
- Basic oxygen furnace (BOF): The iron from the blast furnace is converted into steel in a BOF. Thus, the modern process of manufacturing steel from iron involves a process called "blast reduction."
