Extraction of Iron Metallurgy Blast Furnace and Reactions

A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.

Blast Furnace (U.S. National Park Service)

The blast furnace is where bog ore was smelted to create cast iron "pig" bars. To do this, three types of raw materials were brought over the charging bridge and loaded into the chimney of the furnace. Bog ore is an iron-rich rock that was harvested locally from bogs and similar bodies of water.
