[0002] Incineration residue refers to the total of slag, leakage residue, boiler ash and fly ash generated in the process of garbage incineration. The residue of municipal solid waste incineration treatment plant mainly includes two parts: slag produced by incinerator and fly ash collected by dust collector. Incineration ash contains a certain amount of heavy metal substances, which will pollute the environment if not properly treated.

[0003] The residue generated in the incineration process is generally inorganic matter, mainly metal oxides, hydroxides and carbonates, sulfates, phosphates and silicates. A large amount of residue, especially the residue containing heavy metal compounds, will cause great harm to the environment. Many countries fill or solidify landfill treatment for incineration residue. Due to the limited land resources and the presence of useful substances in the residue, developed countries have long regarded incineration residue as a resource for development and utilization. Valuable metals can be recovered from incineration residue by incineration method, such as recovering silver from waste color paper by incineration method, which has high economic efficiency.

[0004] For garbage incineration residue, wet chemical treatment can be used to recover heavy metals and salts therein. Acid or other dissolving agent can be added to dissolve heavy metals in incineration residue, and then the liquid containing dissolved metals is collected for chemical displacement to extract heavy metals. It is commonly used to recover valuable metals such as gold, silver, rhodium and rare earth elements.
