Iron ores are rocks and minerals from which metallic iron can be economically extracted. Iron (Fe) is one of the most abundant rock-forming elements. It makes up about 5% of the Earth's crust. It is the second most abundant and widely distributed metal (Aluminium is the most common). People have used it for more than 3,000 years.
Unique geological conditions provided the district with closely associated and abundant deposits of iron ore, coal, limestone, and dolomite. These were the raw materials essential for making iron and steel, and at some locations within the district, deposits were only a few miles apart.

The blast furnace is filled with iron ore, coke and limestone. A very hot blast of air is blown in, where it causes the coke to burn. The extreme heat makes the carbon react with iron ore, taking off the oxygen from iron oxides, and making carbon dioxide. The carbon dioxide is a gas and it leaves the mix. There is some sand in with the iron.

There, massive quantities of charcoal fuel, iron ore, and a limestone flux were off-loaded from river barges and "charged" (placed in alternating layers) in the furnace interior. The furnace was then "put into blast" using preheated, compressed air to reduce the ore at a hotter, more efficient temperature.
Ore: Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit.
