Therefore, the basicity of AOD slag is lower than steel slag. Moreover, AOD slag contains much less iron than steel slag. Hence recovery of iron from AOD slag is not important. Perhaps the most important characteristic of AOD slag is that it contains a high amount of Cr (2.5–4.3%) and some Ni (0.2–0.45%).

What is Slag? There are two distinct types of slag produced at the BlueScope Steel Port Kembla Site; Blast Furnace Slag and Steel Furnace (or BOS) Slag. BLAST FURNACE SLAG. Iron is extracted from iron ore in a blast furnace by a process known as reduction. The raw materials - iron ore, coke and fluxes - are fed into the top of the furnace.

In addition to slag recovery, the liquid furnace slag and ladle slags are generally processed to recover the ferrous metals. This metals recovery operation (using magnetic separator on conveyor and/or crane electromagnet) is important to the steelmaker as the metals can then be reused within the steel plant as blast furnace feed material for ...
