As part of a project funded by the US EPA, through the Western Governors' Association, the recent literature on the prediction of acid drainage from metal mine wastes was reviewed. Static tests such as Acid Base Accounting, Modified Acid Base Accounting, B. C. Research Initial Test, and APP:S Test attempt to quantify the total capacities for a mine waste to produce and consume acid. In kinetic tests (e.g. humidity cells, soxhlet extraction, elevated temperature oxidation, column tests, batch reactor tests, B. C. Research Confirmation Test) mine waste samples are subjected to oxidation and the resultant drainage pH is assumed to reflect that of mine wastes dissolving in the field. This paper summarizes information presented in the recent literature on static tests.
