2018/11/15· The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.
The Iron ore is crushed and broken into smaller pieces, concentrated with gravity separation process (washed with water). Step 2: The raw materials are added into the top of the furnace : Iron ore (Haematite, Fe2O3), Coke (Carbon, C), Limestone (CaCO3)
