Cyanidation Tailings
nounPronunciation: /ˌsaɪ.ənɪˈdeɪʃən ˈteɪlɪŋz/
Mining waste generated from leaching precious metals using cyanide solutions, containing residual cyanide compounds that persist in the environment and present toxicity risks. Remediation requires specialized detoxification processes and long-term containment strategies.
Plain English
Mining waste from using cyanide to extract gold or silver that still contains harmful cyanide chemicals.
Etymology & History
Usage
"The gold mine's cyanidation tailings required a multi-stage detoxification process involving alkaline conditions and oxidation to break down residual cyanide before final disposal."
Style guide notes: Always specify residual cyanide concentration when discussing remediation requirements and timelines.
