Wastes Associated With A Fractured Hard Rock Mine

University of Idaho scientists research under U.S. Bureau of Mines Cooperative Agreement C0278001 constitutes a complex hydrogeological, hydrochemical and metallurgical mine waste management project at an existing Superfund site. Technologies that may prove useful for the extraction of dissolved metals from acid mine water and solid wastes include lixiviation and biosorption. Acid mine water is the major, long-term problem in the valley. We are attempting to delineate the major sources of ground water recharge which feed the acid mine drainage and their hydraulic properties. Grouting of recharge areas may facilitate minimizing the production of acid mine drainage if recharge pathways can be identified.
