IRON AND STEEL SLAG

production data for slag were not available, but iron slag production from blast furnaces was estimated to be 25% to 30% of crude (pig) iron production, and steel furnace slag production was estimated to be 10% to 15% of raw steel production. In 2023, world iron slag production was estimated to be between 330 million and 390 million tons, and

Role of Slag in Converter Steelmaking

 — The hot metal and scrap together influences the SiO2 content of the slag. Every kilogram of silicon reacting with oxygen creates 2.17 kilogram of SiO2. This SiO2 need to be neutralized with lime and calcined dolomite for forming a basic slag. This basic slag causes a loss of 5 kilogram of iron into the slag as FeO.

Mechanism of arsenic distribution and migration during iron …

 — Here, ultrasonic enhancement of NaOH–Na 2 S system is proposed to selectively remove arsenic from iron slag. Ultrasound destroys the agglomeration and encapsulation of zinc-containing iron slag and promotes the liquid-solid interfacial reaction.
