Understanding Iron Ores and Mining of Iron Ore. Iron (Fe) is an abundant and a widely distributed element in the in the crust of the earth, constituting on an average ranging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro.
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.
Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from run-of-mine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores History. A set of Cornish stamps. This section ... This separation technique can be useful in mining iron as it is attracted to a magnet.
