slag most of which was granulated Steel slag produced from basic oxygen and electric arc furnaces accounted for the remainder of sales Slag was processed by 28 companies servicing active iron and steel facilities or reprocessing old slag piles at about 124 processing plants including some iron and steel plants with more than one slag
The iron and steel industry not only produces a large amount of steel but also generates significant amounts of iron and steel slag and CO 2019 the global production of iron slag was 320 384 Mt and the amount of steel slag produced was 190 280 Mt USGS 2020 ; moreover the average CO 2 emissions corresponding to one ton of steel produced by an
Natural minerals such as wollastonite olivine serpentine and alkaline industrial waste including steel and iron making slag coal fly ash and mining waste can serve as feedstock for ex situ carbon mineralization [18] In particular the annual amounts of iron slag and steel slag globally generated were estimated to be 390 Mt and 290 Mt
