The blast furnace produces iron from iron ore. Iron ore and coke are fed alternately from the furnace top, while a blast of hot air is blown from the furnace bottom. The CO2 gas generated by the combustion of coke reduces iron ore to iron. As temperature in the furnace reaches as high as 2000°C, molten iron is removed from the bottom of the ...

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.
