%X Melting tests were conducted in an electric heated furnace to study the melting properties of the fly ash sample taken from municipal solid waste incineration power plant. With temperature rising, apparent color of the fly ash got darker, vitrification phenomena got more and more obviously, and the concentrations of most elements in the samples increased gradually. The effects of liquor/solid (L/S) ratio and pH value of leaching liquor on leaching concentrations of heavy metals of the slag were analyzed. The leaching concentrations of heavy metals in the slag were increased with the increase of liquor/solid (L/S) ratio. Heavy metals in the slag could leach out easily under the acidic and alkaline condition.
