Blast furnace Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with

Iron Ore: From Mining to Processing to Dust Control

Today, the most common method for extracting iron from its ores after mining is coke smelting in a blast furnace at a steel plant. Hot air is pumped into the furnace at the bottom through perforations called tuyeres. This initiates some of the reactions for the smelting that becomes pure–molten iron production.
