Removal of Arsenic During Iron Extraction from Waste ...

2020-9-2  Substantial quantities of openly dumped slag contribute to the absence of recovery and utilization of valuable metals as well as potential environmental pollution to water and soil. Owing to the excessively high arsenic content present in iron extracted from copper smelting slag, we propose a new arsenic removal process in this paper. The results indicate that arsenic sulfides in copper ...

Influence of Ferric and Ferrous Iron on Chemical and ...

2013-12-24  shows that the addition of iron into the solution increased the initial rates of copper extraction (~14%/day in the iron added medium versus 10.5%/day in the non added iron medium) which were followed by leveling off the extraction curves. The flat regions in the last 10 days of iron added cultures were attributed to the passivation of chalcopyrite surface. It can be seen that the yield of cop-per extraction in the ferric medium (36.7%) was signifi-cantly lower than that obtained in the experiment with no iron addition (43.1%) and one that ferrous iron was added (41.5%). Copper extraction rates in the last 10 days were 0.02%, 0.18% and 1.1% day in the ferric, fer- rous and non added iron media, respectively. Figure 9 shows that in the ferric added medium the amount of dissolved iron
