the iron mineral in the single magnetic iron ore is mostly magnetite. because the magnetite ore has simple composition,strong magnetism and easy to separate, so the weak magnetic separation process is often used to deal with single magnetic iron ore.2) polymetallic magnetic iron ore weak magnetic separation froth flotation process
usually, the polymetallic magnetic iron ore often contains cobalt silicate, carbonate minerals, pyrite, chalcopyrite and apatite. it is recommended to adopt weak magnetic separation froth flotation process to the extraction of iron ore, namely recycling the iron by the weak magnetic separation process, then recysee more on miningpedia extraction of iron concentration of ore an overviewsep 23, · sep 23, · the extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. the common ores of iron are iron oxides. these oxides can be reduced to iron by heating them with carbon in the form of coke. heating coal in the absence of air produces coke. lecture 1 metal extraction requirements sachinmetal grade is used to characterize an ore reserve. for example metal grade of iron in pure fe2o3 is 70%. if iron ore contains 80% fe2o3 , then iron grade of ore in 56%. this means that 44% of the ore is waste both in terms of solid and oxygen of the valuable mineral.extraction of iron concentration of ore an overviewsep 23, · concentration of ore. the extraction of iron begins with concentration through calcination which is a process in a supply of oxygen applied to ores to bring thermal decomposition. an ore of a metal is an impure source. it consists of many impurities other than metal such as sand, clay, etc.estimated reading time 7 minsiron ore mining techniques metal extractionextracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy. the steps need the ore to be concentrated first, followed by the extraction of the metal from the concentrated ore after which the metal is purified. how is iron extracted from its ore? iron is concentrated by the process of calcinations.
