METHOD OF RECOVERING Fe FROM STEEL-MAKING SLAG

08/01/2015 · The present invention relates to a method of controlling the iron (Fe) content in slag, and more particularly, to a method of recovering Fe from steel-making slag (eg electric furnace slag) by effectively reducing the amount of Fe contained in the electric furnace slagMetal Recovery from Steelmaking Slag,containing 7% Fe and 04% Mn In order to make the iron-rich product recyclable, its grade needs to be improved It was demonstrated that this is possible by grinding the roasted slag to a smaller particle size Liquid-state oxidation yielded poor results, likely due to rapid cooling of slag following its oxidation that did not allow growth and segregation of iron-bearing minerals It was An Experimental Study on Iron Recovery from Steelmaking ,Not only copper and lead blast furnace slag but also converter slag of iron shows high Fe content Morita et al firstly invetigated the recovery of metallic iron from the converter steelmaking
