iron ore extraction methods

Iron Ore Mining Techniques Metal Extraction

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Iron Ore Extraction Methods Mining, Crushing,

Iron Ore Extraction Methods . BY kefidchina February 26th, 2013 . 0. Iron is mined almost exclusively in surface operations. The most predominant surface mining methods used to extract iron ore are open-pit and open-cut methods. The decision to employ underground or surface mining techniques is dependent on the proximity of the ore body to the surface. Underground mining methods, including

The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source as you will see below.
