energy consumption. Therefore, a semismelting reduction and magnetic separation process is an effective method for iron recovery from solid wastes and lowgrade iron ore. In this study, semismelting reduction and magnetic separation technology was employed to recover iron and alumina slag from iron rich bauxite under a lower basicity condition.
The target of the current work is to investigate the possibility of nickel recovery from EAF slag by magnetic separation To meet the target, the effect of the following parameters was studied: grain size, magnetic field intensity, thickness of slag layer, moisture content, and regrinding of the coarser slag
Recovery Improvement of Fine Iron Ore Particles by ... Bentham Open. Apr 9, 2009 ... To recover this fine, Multi Gravity Separator was used in place of Table and was found to ... slag formation during smelting, that in turn requires a high coke rate [4]. There is a vast ... using wet high intensity magnetic separators followed by ....
Abstract. 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.
Magnetic Roll Separator. Magnetic Roll Separators from Star Trace are the most trusted magnetic separation equipment followed by umpteen numbers of industries to separate ferrous from non ferrous substances. The Magnetic Roll Separator uses powerful rare earth magnets that perfectly segregate feeds; this is made possible by the properties and special series of magnet used.

Iron recovery from a lead slag in Henan province was carried out with the technique of coalbased direct reduction followed by magnetic separation. Scanning electron microscopy (SEM) was used to investigate the transformation of ironcontaining minerals and the particle size of metallic iron generated by coal reduction. The results showed that technique is feasible for iron recovery from the ...
magnetic separation. 3 Results and discussion Effect of basicity on selective reduction−magnetic separation The effects of basicity (mass ratio of CaO to SiO2 in the mixture of nickel slag, additive and calcite) on the metal grade and the metal recovery from the nickel slag
Apr 01, 2019· An innovative technology for direct reductionmagnetic separation with the addition of Na 2 CO 3 and CaO was studied to upgrade copper slag assaying % Fe total and % Cu. It is difficult to recover iron and copper from the slag by direct reduction since the iron mainly occurs in fayalite and the copper exists in copper sulfide.
energy consumption of the smelting reduction is too high. By using DR followed by a magnetic separation process for iron recovery from copper slag, Yang [10] obtained iron powder of % iron content with an iron recovery rate of %, and Wang [11] obtained iron powder of % iron content with an iron recovery rate of %.
Steelmaking Slag Beneficiation by Magnetic Separator and Impacts on Sinter Quality Ö. S. Bölükbaşı1, B. Tufan1* 1Department of Mining Engineering, Dokuz Eylül University, 35160, Izmir, Turkey Abstract: Basic oxygen furnaces (BOF) slag is the main problem at all iron and steel factories.
In the magnetic separation process proposed in previous papers,5,7) compositions of recovered phosphorus concentrate and residue vary according to average compositions of slag, cooling methods, and magnetic separation methods; each of these factors is not determined uniquely. Although clarification of the relationships among them is an issue for
Copper slag is a solid waste that has to be treated for metals recovery In order to recover iron from copper slag, the technology of carbothermic reduction and magnetic separation was developed During the reduction roasting, additive CaO reacted with Fe2SiO4 of copper slag, forming CaOSiO2 and 2CaOSiO2, which ameliorates the separation between ...
Metal Recovery from Steelmaking Slag Qi Yu Master of Applied Science Materials Science and Engineering University of Toronto 2018 Abstract An experimental study was carried out to recover metal values from a steelmaking slag through air oxidation and magnetic separation. The oxidation of slag was carried out in both solid and
Jan 10, 2014· 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 scraps.
Recovery of high grade iron compounds from LD slag by enhanced magnetic separation techniques ... that can then be recovered by magnetic separation ... from solidified slag by magnetic separation.
Jul 28, 2016· In this research, the authors aimed at enhancing iron recovery from the steelmaking slag fines by process optimization of upgrading the slag fines with dry magnetic separation. The key operating parameters considered in the upgrading process included magnetic drum radius, drum rotation speed, surface magnetic field strength, gradient of the ...
magnetic separation. Case studies Several case studies are presented that describe the testing and flowsheet development work that enabled proper magnetic separation technology selection and flowsheet configuration. Case Study 1: Dry magnetic separation of ilmenite before electrostatic separation The deposit for Case Study 1 was a typical aeolian
gravity and magnetic separation of lead and zinc slag material magnetic separation of lead and zinc slag material. magnetic separation of lead and zinc slag material SlagWikipedia Slag is the glasslike byproduct left over after a desired metal has been separated (, smelted) from its raw ore.
magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions of 04 and 422 mm. Coarser fractio ns are handled by a heavy media separation the DWPmethod. A magnet separator and spiral washing are used for finegrained material. The recovered alloy of 04 and 422 mm are saleable products.
