Arsenic Removal and Recovery from Copper Smelting ...
Arsenic Removal and Recovery from Copper Smelting ...

Removal and recovery of high levels of arsenic (As) in ,copper, smelting ,wastewater, present a great environmental challenge. A novel approach was investigated for the first time using TiO2 for As adsorptive removal from ,wastewater, and subsequent spent adsorbent regeneration and As recovery using NaOH. EXAFS results demonstrate that As(III), as the only As species present in the raw water, …

Zinc and Copper Recovery from Smelter Waste Stream Case Study
Zinc and Copper Recovery from Smelter Waste Stream Case Study

One of the issues facing the smelter is the lack of a cost-effective and robust process to recover zinc from the ,acidic, process waste stream. As such, significant amounts of zinc-,containing wastewater, are neutralized with lime, resulting in not only the loss of zinc metal but also the generation of large volumes of sludge.
