Leachate Generation
nounPronunciation: /ˈliːtʃeɪt ˈdʒɛnəˌreɪʃən/
The process by which water percolates through mine waste materials, dissolving and mobilizing contaminants including metals, sulfates, and salts. The rate and composition of leachate depend on waste mineralogy, moisture content, temperature, and pH conditions within the waste mass.
Plain English
Water that picks up contaminants as it seeps through mine waste materials.
Etymology & History
Usage
"Minimizing leachate generation is a primary objective in designing engineered covers for abandoned mine waste."
Style guide notes: Use 'leachate generation' when describing the process; use 'leachate' for the actual liquid product.
