Abstract: The main chemical compositions and occurrence state of open-circuit dust in copper
smelter were reviewed in this paper. Three processing techniques including pyrometallurgical process,
hydrometallurgical process and pyro–hydrometallurgical process to recover the dust comprehensively
were discussed, and the advantages and disadvantages of them were systematically compared. On the
whole, the hydrometallurgical processing is effective and flexible for treating such materials because of its
good working environment, wide application range, low energy consumption, rich technical means, etc,
and thus has a good prospect of industrial application on comprehensive recovery of open-circuit dusts
in coppersmelter.
