These are oxides of iron that are extracted from beneath the surface of the earth’s crust and sent to blast furnaces to make pig iron. Bog iron is much easier to smelt because it contains fewer impurities than iron ore in rock deposits, but the quantity of iron available from bog iron is relatively low (although actually renewable, unlike mines; a bog can be harvested for iron again after a few decades as the processes which produce the bog iron continue). Most of the iron ore produced in the world is extracted from the earth’s crust through opencast mining.

The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. The remaining rock is waste material and is dumped into tailings basins. This slag was repeatedly hammered and heated to extract iron. Types of iron ore. to mine and process as they require less beneficiation due to the higher iron content. Iron is one of the most common elements on earth. The most commonly found ores of iron are Hematite and Magnetite. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. What is iron ore? Whaleback, Yandi, and Area C mines are shown. Mechanized mining involves creation of benches that are used for the purpose of drilling, blasting, and finally the transportation of the iron ore to the crushing plant. Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. Nearly every construction of man contains at least a little iron. Iron ore is mined in about 50 countries.
