By using a series of tests for corrosivity, acute toxicity and leaching toxicity of cyanide-containing wasteresidues, the toxicity of cyanide-containing wasteresidues has been investigated. According to acute toxicity test, the wasteresidues showed no acute toxicity. The experiment further indicated that the cyanide compounds were tested in the 0.15 ~ 0.60 concentration rang, mean (0.429), standard deviation (0.195) and variation coefficient (45.5%). The pH value range for leaching liquor of slag yard was 9.21~13.09 at the mean 10864, and the standard deviation and variation coefficient were 1.553 and 14.3% respectively. The research revealed that the cyanide compounds content in wasteresidue samples was distributed very unevenly, and the content of cyanide compounds was not exceeded the standard. Based on the current analysis results, those cyanide-containing wasteresidues were defined as hazardous solidwastes with corrosivity.
