Abstract

The slag from high temperature smelting of copper sludge, electroplating and pickling sludge in different cooling methods were studied for the heavy metal removal and solidification effect. The contents results showed large removal of Cu, Ni, Cd and serious enrichment of Mn, Ba, Be, Pb, As. The leaching results showed the best solidification effect of Cu, Ni, Cd and the poorest of Ba. XRD showed more crystal structures in RW and JF, while little in SH and MF, which had no different effect on solidification. SEM-EDS results showed dense surface in copper sludge disposal enterprises' slag samples, and various-materials surface in electroplating and pickling sludge disposal enterprises' slag samples. The solidification effect of slag produced from smelting sludge was poor in acid environment while better in weak acid to alkaline environment.
