In this research, it is confirmed that monosodium glutamate effectively extracted nickel (Ni) from electric arc furnace dust (EAFD) in alkaline conditions. The condition favorably recovered Ni, while other elements, especially Al and Fe, were enriched in solid residue. The optimum condition to recover Ni was at pH 8-9, MSG concentration 1 M, and pu...

Electric arc furnace dust (EAFD) is a potential secondary source of nickel (Ni). Although Ni content (0.5%) is much lower than traditional ore i.e. laterites, EAFD as raw material has advantage in terms of straightforward processing. It was demonstrated that Ni could be directly recovered from EAFD by leaching using glutamate in alkaline condition....

Slag as the secondary product (waste) of tin smelter still contains not only valuable elements e.g. rare earth elements but also radioactive such as Th. Both radioactive elements are accumulated in the slag phase since the raw materials used in smelting i.e. cassiterite minerals, is closely associated with Th and U containing monazite. Due to valua...
