The ore bed was then covered by further volcanic deposits (quartz porphyry) and sedimentary rocks before being tilted to its current dip of 5060°. The ore contains a very pure magnetiteapatite mix, containing more than 60% iron and an average of % phosphorus. Black ore contains less apatite than grey ore.

Use of Magnetite as an Ore of Iron. The concentrate is then mixed with small amounts of limestone and clay, then rolled into small round pellets. These pellets are easy to handle and transport by ship, rail, or truck. They can be directly loaded into a blast furnace at a mill and be used to produce iron or steel.
solubility of phosphorus in these minerals is substantially lower and they are concentrated along the newly formed cracks and surfaces as blebs, as reported by Gooden et al (1973, 1974). Muhammed and Zang (1989) have used nitric acid (6M) leaching for 24 hours of a magnetite iron ore containing 1
Apr 26, 2013· Production of iron from iron ore (hematite magnetite) . coke, and a flux such as limestone (which is used to remove impurities in the ore which would . Common fluxes include limestone (principally calcium carbonate) and dolomite (CaCO3.
High Phosphorus Magnetite Iron Ore Uses high phosphorus magnetite iron ore uses . Iron ore Wikipedia, the free encyclopedia Chilean magnetite iron ore deposits within the Although bar iron is usually worked hot, its uses often There are two remedies for high phosphorus iron. get more information.
Magnetite is the principal iron ore mineral, although some areas contain significant amounts of haematite. Apatite contents vary considerably from orebody to orebody, with the average phosphorus content lower than %. As of the end of 2009, Malmerbeget's proven and probable iron reserves totalled 350Mt at % (proven) and % (probable).
Micaceous iron ore, which is a variety of hematite, is used as a coating material in the preparation of welding rods (electrodes). Pig iron ore (Fe 3 OH 6) is used as a purifying and de – sulphurizing material of producer and municipal gases. Magnetite is used for .

Formula For Finding Fe N Magnetite Ore Formula For Finding Fe N Magnetite Ore. Magnetite Wikipedia. Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.
Highphosphorus oolitic iron ore, treated by suspended flash magnetic roasting, contained % iron (mainly present as magnetite) and % phosphorus (present as collophane). Lowintensity magnetic separation (LIMS) was combined with reverse flotation to increase the iron and reduce the phosphorus contents of the roasted product.
