An overview of recovery of metals from slags - ScienceDirect

2003-01-01· Iron slag is generated from Blast Furnace (BF slag) in the iron production, with 220–370 kg slag per ton of iron being produced (Proctor et al., 2000). The amount of BF slag is the largest among the ferrous slags. For example, In USA and Japan, 13 and 24.3 million tons of BF slag were produced each year (Proctor et al., 2000, Okumura, 1993).

Two main production methods are involved (Fig. 1). In the iron ore-based process, pig iron is produced from oxidic iron ores in a blast furnace. In an LD oxygen converter the molten pig iron is then processed together with steel scrap into crude steel. In the purely scrap,
