Mar 14, 2014· The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.
4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low …
The zinc content of mined ore is usually between 3 and 10 percent. Almost all ores contain the lead sulfide mineral galena and small quantities of cadmium sulfide. Chalcopyrite, and copper-iron sulfide, is often present. The most common gangue constituents are calcite, dolomite, and quartz. Mining and concentrating
Feb 19, 2014· The Karara mine located about 220km east of Geraldton in Western Australia holds 955 million tonnes of iron ore (36.4% Fe) and is the tenth biggest iron ore mine in the world.

Iron Ore. Iron (Fe) is a metallic element which constitutes about 5% of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ).
Oct 23, 2017· The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).
