Spherules in iron slag
Web27. dec 2015 · Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten crude iron or steel; the slag is then removed from the liquid metal. For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about 0.25 to 0.30 metric tons of slag per ton of crude iron produced.
