Tailing Impoundment
nounPronunciation: /ˈteɪlɪŋ ɪmˈpaʊndmənt/
A constructed or natural basin designed to contain and settle fine mining waste particles and associated process water. Tailing impoundments serve as temporary or permanent storage for mill tailings, allowing separation of solids from liquids before eventual reclamation or closure.
Plain English
A storage area where finely ground mining waste and water are held to let solids settle.
Etymology & History
Usage
"The abandoned tailing impoundment required complete remediation, including decanting standing water and consolidating settled solids."
Style guide notes: Use 'tailing impoundment' for water-based storage and distinguish from dry-stack alternatives in reclamation documents.

Frequently Asked Questions
Why are tailing impoundments used?
They separate fine solids from water through gravity settling, reducing the volume and handling of waste streams.
What are reclamation challenges for tailings ponds?
Challenges include seepage control, consolidation time for thick tailings, and management of residual contaminated water.
Why Test Candidates on This?
Understanding tailing impoundment reclamation is essential for addressing water quality, geotechnical stability, and closure planning.
