25.2 Extracting ores Mining of mineral resources Siyavula

Iron ore, coke and lime are added to the top of a furnace. Hot air is blown in from the bottom. The furnace operates at a high temperature (around 1200°C). Iron ore reacts with carbon/coke to form iron metal and carbon dioxide. The iron is tapped off at the bottom of the furnace.
