Heap Leach Pad Remediation
nounPronunciation: /hiːp liːtʃ pæd ˌriːmədiˈeɪʃən/
The process of treating and stabilizing ore processing areas where minerals were extracted using solution percolation methods, involving removal or encapsulation of residual chemical solutions and contaminated materials. This remediation prevents leachate migration into groundwater and soil systems.
Plain English
Cleanup of mining areas where chemicals were used to extract metals from piled ore, preventing toxic liquid from spreading.
Etymology & History
Usage
"The gold mining site required extensive heap leach pad remediation to eliminate risks from residual cyanide solutions left in the soil."
Style guide notes: Always specify the chemical leachant used (e.g., 'cyanide heap leach pad') when discussing remediation approaches.
