· Potentially acid-generating (PAG) waste rock is defined in Nevada, USA as material with an acid–base accounting (ABA) ratio < 1.2, based on the acid neutralizing potential (ANP) to acid generating potential (AGP) ratio. However, waste rock humidity cell tests (HCTs) used to define PAG often fail to release the anticipated acidity. For example, the pH, Fe, and SO4 data from 150 lithology ...
