Recirculation of high arsenic content copper smelting

2013-8-1 · 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.

The removal of arsenic from water using natural iron

2012-7-1 · Hematite exhibited the lowest arsenic adsorption, however its addition to the solution was much lower than that of the other mineral samples (0.5 g per 100 mL as compared to 10 g per 100 mL). As a result, the loading of arsenic onto hematite was much higher when expressed as arsenic adsorbed per mass or per surface area of the adsorbent.
