Acid-Generating Potential (AGP)
nounPronunciation: /ˈæsɪd ˈdʒɛnərətɪŋ pəˈtɛnʃəl/
The capacity of sulfide-bearing minerals within mine waste or tailings to produce sulfuric acid upon oxidation, quantified through static testing methods. AGP is essential for predicting long-term water quality impacts and designing appropriate mitigation strategies.
Plain English
A measure of how much acid will be produced when sulfide minerals in mine waste oxidize over time.
Etymology & History
Usage
"Laboratory AGP testing revealed the tailings impoundment has moderate acid-generating potential requiring a lined containment system."
Style guide notes: Use parenthetical expansion (AGP) on first use; abbreviate thereafter in technical documents.

Frequently Asked Questions
How is acid-generating potential measured in laboratory tests?
Using static tests like paste pH, net acid production, and sulfur speciation analysis on mine waste samples.
What materials have high acid-generating potential?
Pyrite, chalcopyrite, and other metal sulfides exposed during mining have significant AGP values.
Why Test Candidates on This?
AGP determination is fundamental to baseline geochemical assessment required before reclamation design approval.
