Abstract: Selective extraction technology was used to extract Fe oxides and Mn oxides from surface coatings. The concentrations of Fe, Mn, Pb, Cu and Zn after extracting were measured to study the enrichment of Pb, Cu and Zn on Fe oxides, Mn oxides and other components. The results show that Mn oxides contribute most to Pb enrichment and the contributions of Fe oxides and other components are relatively small. For Cu enrichment on each component, the contributions of other components are significantly higher and the contributions of Fe oxides are similar to the that of Mn oxides. The contributions of Mn oxides to Zn enrichment are higher, while the contributions of Fe oxides are close to the contributions of other components. The Pb, Cu and Zn enrichment abilities of Mn oxides are bigger than the enrichment abilities of Fe oxides. The Pb, Cu and Zn enrichment abilities of Fe oxides and Mn oxides follow this order respectively: Zn>Cu>Pb, Zn>Pb≥Cu.
