I-Silicon Slag yimveliso ye-slicle inyibilikisi kunye ne-ferrosilicon.it luhlobo lwesiko elivela kwi-scum kwinkqubo ye-sclicon.it ivela kwi-45%, phes, fe, fe, fe, fe, fe, fe, ca. Kuyinto enexabiso eliphantsi kune-chalty inyibilikisi. Endaweni yokusebenzisa i-ferrosilicon ye-Steeelmenking, inokunciphisa iindleko.
