Oxidation Buffering
nounPronunciation: /ˌɒksɪˈdeɪʃən ˈbʌfərɪŋ/
The application of alkaline materials to neutralize acidic conditions generated by sulfide mineral oxidation in mine waste and tailings. This process maintains pH stability and reduces the formation of acidic mine drainage through chemical equilibration.
Plain English
Adding alkaline substances to prevent acid formation from oxidizing minerals in mine waste.
Etymology & History
Usage
"The remediation team employed oxidation buffering using limestone to prevent acidic drainage from the exposed sulfide deposits."
Style guide notes: Specify the buffering agent and target pH range when discussing oxidation buffering methods.
