What's weathering? Mineralogy and field leach studies in mine waste, Leadville and Montezuma mining districts, Colorado What's weathering? Mineralogy and field leach studies in mine waste, Leadville and Montezuma mining districts, Colorado
Weathering is important in the development of rock fabrics that control porosity in mine-waste materials, and in turn, porosity affects metal transport through and from mine-waste piles into watersheds. Mine-waste piles are dynamic physical and chemical systems as evidenced by remnant Fe-oxide boxwork structures after sulfide minerals, development of alteration rinds and etch pits on...

Predicting toxic effects of copper on aquatic biota in mineralized areas by using the Biotic Ligand Model Predicting toxic effects of copper on aquatic biota in mineralized areas by using the Biotic Ligand Model
The chemical speciation of metals influences their biological effects. The Biotic Ligand Model (BLM) is a computational approach to predict chemical speciation and acute toxicological effects of metals on aquatic biota. Recently, the U.S. Environmental Protection Agency incorporated the BLM into their regulatory water-quality criteria for copper. Results from three different laboratory...

Integrating bioavailability approaches into waste rock evaluations Integrating bioavailability approaches into waste rock evaluations
The presence of toxic metals in soils affected by mining, industry, agriculture and urbanization, presents problems to human health, the establishment and maintenance of plant and animal habitats, and the rehabilitation of affected areas. A key to managing these problems is predicting the fraction of metal in a given soil that will be biologically labile, and potentially harmful (...

The use of synthetic jarosite as an analog for natural jarosite The use of synthetic jarosite as an analog for natural jarosite
The presence of jarosite in soil or mining waste is an indicator of acidic sulfate-rich conditions. Physical and chemical properties of synthetic jarosites are commonly used as analogs in laboratory studies to determine solubility and acid-generation of naturally occurring jarosites. In our work we have mineralogically and chemically characterized both natural and synthetic jarosites...

Comparison of mine waste assessment methods at the Rattler mine site, Virginia Canyon, Colorado Comparison of mine waste assessment methods at the Rattler mine site, Virginia Canyon, Colorado
In a joint project, the mine waste-piles at the Rattler Mine near Idaho Springs, Colorado, were sampled and analyzed by scientists from the U.S. Geological Survey (USGS) and the Colorado School of Mines (CSM). Separate sample collection, sample leaching, and leachate analyses were performed by both groups and the results were compared. For the study, both groups used the USGS sampling...
