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.

Bog ore is an iron-rich sedimentary rock that was harvested locally from bogs and similar bodies of water. It was also found in fields and meadows that used to be bogs. Bog ore is often considerably less than 50% iron. The rest of the rock was made up of impurities that the workers had to remove. Gabbro was used as a flux;a way to purify the ore.
