Approximately 40% of the zinc consumed worldwide comes from recycled or secondary zinc. For the zinc and steel industries, recycling of zinccoated steel provides an important new source of raw material – both zinc and steel can be recycled again and again without any loss of their physical or chemical properties. Zinc is recycled at all stages of production and use, .

In orebased steelmaking, blast furnace (BF) dust is generally recycled to the BF via the sinter or coldbonded briquettes and injection. In order to recycle the BF sludge to the BF, the sludge has to be upgraded, removing zinc. The literature reports cases of recycling the lowzinc fraction of upgraded BF sludge to the BF. However, research towards recycling of the highzinc fraction of BF ...
