Recirculation of high arsenic content copper smelting dust ...

Aug 01, 2013  The results presented in Fig. 8 show that the distribution of As, Pb and Zn in the blister decreased when the dust addition ratio increased. The presence of multiple phases enhances the elimination of Pb and Zn. During the second stage of converting, the vapor pressure of As species is low and for that reason the volatilization decreased.
