Electronic waste (e-waste) accumulation on earth is a serious environmental challenge. The
need for heavy metal recovery, together with the profitability of precious and base metals …

Smelting dust is a toxic waste produced in metal-mineral pyrometallurgical processes. To
eliminate or reduce the adverse environmental impacts of smelting dust, valuable …

Mine tailings often contain significant amounts of metals and sulfide, many traditional
operations used to minerals was not as good as those currently available. This study …

In view of reducing contaminant and recovery arsenic and antimony, a novel technology was
proposed to recover arsenic and antimony from arsenic-rich copper smelter dust …

Although copper (Cu) is an essential micronutrient for all living organisms, it can be toxic at
low concentrations. Its beneficial effects are therefore only observed for a narrow range of …

Recovery of bismuth and arsenic from copper smelter flue dusts after copper and zinc
extraction was carried out by a hydrometallurgical process. The dusts were leached with a …

Separation of arsenic and extraction of zinc and copper from high-arsenic copper smelting
dust (HACSD) is one of the difficulties in the world. A two-stage countercurrent alkali …

Arsenic is selectively extracted from high-arsenic dust by NaOH–Na 2 S alkaline leaching
process. In the leaching arsenic process, the effects of alkali-to-dust ratio, sodium sulfide …

A clean and efficient hydrometallurgical process was developed to recover Cu, Zn, Cd, Bi
and Pb from the hazardous solid waste of copper smelting open-circuit (CSO) dust using the …

Modern industries that are involved in the design and development of high-technology
products rely heavily on the availability of critical materials. As a result, there has been a …
