Abstract Scope |
Incineration is an advanced solid waste management for municipal solid waste. MSWI is an efficient combustion process of the waste disposal/treatment. Municipal solid waste incineration (MSWI) fly ash and bottom ashes are the byproducts of incineration combustion process. In particular, incineration of waste samples containing valuable nonferrous metals such as copper (Cu), zinc (Zn), lead (pb), nickel (Ni), titanium (Ti), including heavy metals arsenic (As), chromium (Cr), cadmium (Cd) and mercury (Hg) etc, critical rare metals and rare earth elements. We collected the copper rich four different municipal solid waste incineration bottom ash samples from four different incineration plants from Seoul, Korea. The investigations were carried out at bench scale. For copper extraction using sulfuric acid is more suitable with high efficiency. In this work, we used LIX extractant for selective extraction of copper from bottom ash samples. Finally, an efficient recovery of the copper was extracted 90% was achieved. |
