Blast furnace process - tec-science
If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures. The carbon (\(C\)) is oxidized to carbon monoxide (\(CO\)) by the absorption of oxygen (\(O\)).

THE BLAST FURNACE - IRON PRODUCTION
The stock level is constantly ‘topped up’. Molten iron ore is ‘tapped’ at the bottom of the blast furnace, poured into the iron ladle and removed for use. The slag is removed at the tap hole. Although generally regarded as waste, it is used in road making.
Generation of iron and steel slag : NIPPON SLAG …
Blast furnace slag is a coination of silica and other non-ferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered.
