Estimation and prediction as to whether waste rock and tailings will produce acid mine drainage (AMD) are precursory to environmental certification, and therefore are a critical step in mine development. Kinetic tests are carried out using a cell or column that are operated over a period of typically 1 year, whereas static tests are a onetime measurement to determine the acid producing potential (AP) and... [Pg.83]

Jarosites are generally less soluble in acidic waters than under alkaline conditions. Although As(V) is known to partially substitute for sulfate in the mineral (Savage, Bird and Ashley, 2000), controversies exist over whether jarosites preferentially sorb more arsenic than their frequent decomposition product, goethite (Acero et al., 2006, 4137-4138). Examples of exceptionally arsenic-rich jarosites occur in mine tailings at Enguiales, Aveyron, France, where arsenic concentrations are approximately 5.7 wt% (Courtin-Nomade et al., 2003). [Pg.109]

Mine tailings Rocks, minerals, sediments, soils, and other wastes that result from the mining of ore deposits or coal. Mine tailings often contain pyrite and other sulfide minerals, which oxidize in the presence of oxygen and water to form acid mine drainage. [Pg.457]
