Iron ore mining is classified into two categories manual mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the iron oxide in a blast furnace to give iron as a result.
Several methods/techniques such as washing, jigging, magnetic separation, gravity separation, and flotation etc. are used to enhance the Fe content of the Iron ore and to reduce its gangue content. These techniques are used in various combinations for the beneficiation of iron ores.
The beneficiation of chromite and iron ore using gravity and magnetic separation followed by flowsheet design have become important activities. Services. Heavy Liquid Separation and DenseMedia Separation. Laboratories have been set up to carry out preliminary "sinkfloat" separations up to densities of 4 g/cm³.

Iron Ore: Mineralogy, Processing and Environmental Issues . summarizes recent, key research on the characterization of iron ores, including important topics such as beneficiation (separation and refining), agglomeration (, production of pellets or powders), blast furnace technology for smelting, and environmental issues relating to its production.
Sep 30, 2012· Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to ...
The Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.
This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina, Tasmania, magnetic separation was used to separate the ores.
There are two distinct categories of iron ore mining, surface mining such as open cast or strip mining and underground mining. At the surface iron ore processing plants, the iron ore is put through crushers and ball mills to break it into a uniform and more workable size .
