The flux slag recovered after crushing magnetic separation of steel slag has been used by the sinter plant, and the ratio is generally about 115% However, the blending of flux slag will affect the grade and quality of sinter, mainly because the water wetting property and pelleting performance of the steel slag are worse than that of iron ore Importantly, the recycling efficiency of iron from steel slag with an acid extraction is improved significantly due to a simultaneous increase in the recovery of ironrich materials and the iron content of the materials recovered Highquality iron ore with iron content of 551–706% has been recovered from waste slag Highly efficient CO2 capture with simultaneous iron About 45 to 55% steel slag can be used for the 23% The generation and quality of steel slag varies wit 153 2017, Vol 26 ) ), India get rid of completely developed general environmental llution around 30%, unt of steel slag goes to erated in Steel As of 63% are dumped steel slag in it is preferred as a In general, the iron h theReuse of Steel Stag for Resource Conservation and The sintering or reductivesintering of bauxite residue has also been explored in literature [7,11,14,17,18,19], but inefficient separation of varied magnetic iron phases often hinders iron recovery However, sintering and reductivesintering are able to recover aluminum and sodium without suffering sodium gaseous losses when smelted at high Minerals Free FullText Sintering Optimisation and iron, carbon monoxide (CO), and slag (a molten liquid solution of silicates and oxides that solidifies upon cooling) The molten iron and slag collect in the hearth at the base of the furnace The byproduct gas is collected at the top of the furnace and is recovered for use as fuelTechnical Support Document for the Iron and Steel Sector
