We will discuss the extraction of iron from iron ore as an example. Extraction of iron. Iron atoms are found in the compounds FeO, Fe 2 O 3 and Fe 3 O 4 and in rocks like haematite and magnetite. South Africa is the seventh largest producer of iron ore in the world. Iron has been mined in South Africa for thousands of years.
In hard rock mining, much of the world's annual output of copper, gold and iron ore is won from open-pit operations. Other commodities produced from open-pit mining include diamonds, molybdenum, manganese, lead and zinc, uranium and a variety of industrial minerals, such as borates, talc and specialist clays.
