Metallurgical Residue Encapsulation
nounPronunciation: /ˌmɛtəˈlɜrdʒɪkəl ˈrɛzɪˌduː ɛnˌkæpsjəˈleɪʃən/
A containment strategy that seals or encloses mining byproducts and processing residues within engineered barriers to prevent leaching and environmental release of metal concentrates. Encapsulation methods include geosynthetic membranes, solidification/stabilization matrices, and multilayer cap systems.
Plain English
Sealing mining waste in protective barriers to stop metals from leaking into soil and water.
Etymology & History
Usage
"Metallurgical residue encapsulation with clay-lined composite barriers prevented tailings leachate migration."
Style guide notes: Distinguish between encapsulation and capping; encapsulation implies complete isolation versus surface protection only.
