the mineral is often mined as an ore of iron, and lately, through the use of magnetic separator processing plant and chemical intervention, magnetite iron sand became a primary source of raw material like iron ore for steel and cast iron manufacturers when they are developed in the form of iron lumps, balls, fines, and pellets.the magnetite-apatite ore of the kiruna district, northern sweden fig.2 geological map of the kiruna district showing the setting of the iron ores kiruna luossavaara rektorn henry haukivaara nukutusvaara and tuollovaara the characteristic footwall rocks are trachyandesitic lavas traditionally
production of iron from iron ore It almost always consists of iron oxides, the primary forms of which are magnetite and hematite the first stage is to produce pig iron haematite ore mines in odisha. mining & beneficiation. like haematite, magnetite is not found in such high grades so as to be used as dso. the ore is beneficiated for magnetite recovery. magnetite ores have mere iron content and as such, cannot be used directly for iron making. It has to be beneficiated to concentrate the iron bearing
mar 29, 2020 It is also used in coal mining operations as a slurry with water to remove the heavier impurities by allowing the less dense coal to float to the surface. the magnetite can be reused in this process percent of the time. magnetite is also used as a source of iron to manufacture iron-based chemicals and fertilizers.feb 22, 2021 christian petersen date: february 22, 2021 magnetite is a source of iron ore which is commonly used in the production of steel.. magnetite is an iron oxide mineral belonging to the group known as spinels. It is a very common and is a valuable iron ore.magnetite has been known to mankind since early history and led to the earliest discovery and understanding of magnetism.

magnetite is rock mineral and one of the most important iron ore minerals with chemical formula is iron oxide, FF .it also as the name magnetic minerals to attracted to a magnet. It is the most magnetic natural occuring minerals in the world. small grains of magnetite occur in almost all igneous and metamorphic rocks.magnetite is an important ore of iron. well formed crystals are popular among mineral collectors, and the magnetic lodestone variety is frequently sold in hobby shops to amateur collectors. magnetite is also of significant interest to the science community due to its strong magnetic properties.
