  • Recovery of high grade iron compounds from LD slag by

      Two variants of magnetic separation were performed on LD slag The first one deals with treatment of ground LD slag at different particle size fractions of 1 mm, 400 μm, 200 μm and 200 μm by dry magnetic separation This technique may be applied on the coarse fraction of LD slag to recover only iron The combination of Low and High Intensity Magnetic Separation (LIMS and HIMS) of ground LD slag at 63 μm in wet process may recover ferromagnetic particles (iron oxides) at LIMS and paramagnetic particles at HIMS, while the nonmagnetic fraction contains mostly calcium silicatesRecovery of high grade iron compounds from LD slag by Magnetic separation Wikipedia Weak magnetic separation Weak magnetic separation is used to create cleaner ironrich products that can be reused These products have low levels of impurities and a high iron load This technique is used as a recycling technology It is coupled with steelmaking slag fines as well as a selection of particle size screeningslag iron magnetic separation maciejadamskipl

  • Recovery of iron from copper slag via modified roasting in

      Based on the above analysis, a new method of recovery of iron from copper slag via modified roasting and magnetic separation is proposed, where the whole system is in a weak oxidizing atmosphere due to stable equilibrium of CO 2 –CO [ 19 ], and ferrous oxide (FeO) in fayalite is separated by adding flux (CaO) [ 20 ], and then the free FeO is oxidized and roasted to magnetite at lower temperatureThis work presents a semismelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized The results show that the iron nuggets and alumina slag can be SemiSmelting Reduction and Magnetic Separation for the magnetic separator to recove iron from steel slag r While, the hematite is weak magnetic mineral, and the iron share is 1835% So, the magnetic intensity should not be too low Although quartz and plagioclase have high iron contents, their iron grade and iron share are relatively low and cannot be recovered in a weak magnetic fieldDRY MAGNETIC SEPARATION TECHNOLOGY FOR THE

  • SemiSmelting Reduction and Magnetic Separation for the

    After magnetic separation, the alumina slag obtained at the optimal process were crushed to a particle size of 80% lower than 74 μm, then the phase composition of the alumina slag was investigated using XRD It was found that the peaks of Fe 2 O 3 disappear completely, and most of the metallic iron is separated through magnetic separation  The magnetic separation method is used for separating metallic iron and iron minerals from steel slag Commonly used magnetic machines are the crossbelt magnetic separator, drum magnetic separator and magnetic pulley separator No one system or type of magnet Application of magnetic separation to steelmaking slags   To improve the efficiency of iron recovery from steel slag and reduce the wearandtear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron (MFe) in the slag The final recycling efficiency was evaluated by calculating the percentage of recycled MFe to the maximum amount of M Optimization of magnetic separation process for iron

    Slag Iron Magnetic Separation Arc Furnace EAF Because iron in the steel slags is normally encountered in the form of steel 710 , iron oxide and iron bearing minerals, the recovery of iron is achieved by crushing or grinding, screening and magnetic separation 17 Similarly to iron slags, steel slags can also be used in other applicationsThis work presents a semismelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized The results show that the iron nuggets and alumina slag can be SemiSmelting Reduction and Magnetic Separation for the   Steelmaking slags are usually processed for iron recovery by dry magnetic separation The recovered ironrich products are recycled back into the ironmaking and steelmaking processes to replace highcost steel scrap and iron ores However, current slag processing is far away from optimum conditions, especially for slag Enhancement of Iron Recovery from Steelmaking Slag

  • Recycling of steelmaking slag fines by weak magnetic

      The ineffectiveness of existing magnetic separators in treating steelmaking slag fines might have two reasons: (1) iron might not be very well liberated from steelmaking slag fines; or (2) industry might have failed to set up effective working conditions for treating steelmaking slag fines with magnetic separation  The particle size of metallic iron can be increased by adding fluxes, such as CaO and Na 2 CO 3, during carbothermal reduction, thereby favoring the increase of the Fe content in concentrate by grinding–magnetic separation8, 12,13,14,15,16,17 Recent studies on iron recovery from reductively roasted copper slag by grinding–magnetic Liberation and Enrichment of Metallic Iron from Slag Iron Magnetic Separation magnetic separation is not an effective tool for processing fine dry materials In addition the nonmagnetic noniron bearing slag fines do not have an existing market demand and the disposal of the fines can be a problem To overcome these obstacles a process Quantitative Determination of Metallic Iron Content in SteelMaking SlagSlag Iron Magnetic Separation ulang
