Recovery of iron from hazardous tailings using fluidized roasting

The iron recovery rate can be calculated as follows: Fe recovery rate = Weight of samples × Fe content of samples Weight of raw ore × Fe content of raw ore × 100 % The iron phase of samples was analyzed by common physical and chemical methods in the field of mineral processing, including magnetic separation, acid leaching and *Corresponding author: Recovery of magnetitehematite concentrate from iron ore tailings Mikhail Khokhulya1,*, Alexander Fomin1, and Svetlana Alekseeva1 1Mining Institute of Kola Science Center of Russian Academy of Sciences, Apatity, , Russia Abstract The research is aimed at study of the probable recovery of iron from Recovery of magnetitehematite concentrate from iron ore

Recovery of iron from vanadium tailings with coalbased direct

Iron tailings, a type of refractory iron ores, pose a challenge for effective iron recovery due to the complex mineral combinations and liberation modes In this study, we proposed a new approach to improve the quality of iron concentrates by combining alkaline leaching with magnetization roastingmagnetic separation, which promoted the However, only iron and vanadium can be extracted in this process and almost all titanium resource remains in slag without effective utilization [7], [8] Moreover, a high percentage of other iron ore need to be added into VTM to prevent the phenomenon of foaming slag in BF process [9]Separation and recovery of iron and titanium from oxidized

Innovative methodology for comprehensive utilization of iron ore

Iron tailings, a type of refractory iron ores, pose a challenge for effective iron recovery due to the complex mineral combinations and liberation modes In this study, we proposed a new approach to improve the quality of iron concentrates by combining alkaline leaching with magnetization roastingmagnetic separation, which promoted the An iron ore concentrate with total iron content of 5634% at the recovery rate of 8805% can be obtained by magnetic tube separation under the roasting conditions of 800℃ for 60 min and slight(PDF) Separation and recovery of iron from a lowgrade

Applications of Dissimilatory Iron Reducing Bacteria (DIRB) for

The nickel present in the low grade nickeliferous lateritic ore is firmly ingrained in the goethite matrix [Fe (III) phase] withstanding its complete recovery by conventional methods [29] The strong retention of nickel in the goethite matrix has been confirmed in many studies by the loss of the metal during goethite precipitation which In our group, the comprehensive utilization of iron ore tailings is the focus of our research, and our final goal is to realize zeroemission of iron ore tailings wastes Based on the above description of different ways of utilization of iron ore tailings, the cost of only recover iron from tailings is high because of the low content of ironInnovative methodology for comprehensive utilization of iron ore
