Flue sintering process Mikkaichi Japanese refining zinc plant by electric heating generated by the electrical dust collecting dust collection is also enriched with cadmium (cadmium 20%), plus the lead smelter Saganoseki EAF dust. Cadmium (Figure 1) was extracted using a sulphation roasting-leaching-displacement-vacuum distillation-melting process to produce 99.999% high purity cadmium.
