Iron ore. iron ore is the primary raw material used to make steel. steel is strong, long-lasting and cost-efficient – making it perfect for everything from washing machines to cars, bridges and skyscrapers. according to the world steel association, steel is the most commonly used alloy in the world. global steel consumption is forecast to mining.
Mining and processing of iron ore involves coarse crushing and screening. iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. this is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.
In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, is also frequently pelletized so it can be utilized, as opposed to disposed of. the pelletizing process. the production of iron ore pellets from fines to finished product can differ based on a variety of mining.
