The Process of Iron Smelting: Turning Iron into Usable Metal

The furnaces produced pig iron in 80-100 pound bars that were five to six feel long and six inches around. The brown hematite ore was originally mined from the ground by pick and shovel. The ore was washed to remove the clay and then the clean ore was hauled by mule to the top of the furnace where it was dumped in a 12-foot opening …

The Direct Reduction of Iron Ore

the ore is smelted, yielding a pig iron con­ taining reduced elements and a slag con­ taining all the oxidized and unreduced sub­ stances. The pig iron is melted and refined in a steelmaking furnace. In this procedure the reduction of iron ore is regarded as an incidental intermediate step, and the reduc­
