Bacterial diversity in mine tailing microbial communities has not been thoroughly investigated despite the correlations that have been observed between the relative microbial diversity and the success of revegetation efforts at tailing sites. This study employed phylogenetic analyses of 16S rRNA genes to compare the bacterial communities present in highly disturbed, extremely (pH 2.7) and ...

The Livingston Mill is an abandoned lead-zinc-silver ore processing facility located in central Idaho near the confluence of Jim Creek and Big Boulder Creek in Custer County. The site is approximately 26 miles southwest of the town of Clayton, Idaho. The ...

The Ford Motor Sludge Lagoon Site has been listed on the National Priorities List. The site includes an abandoned sludge lagoon. To date, identified contaminants of concern on the site include cyanide, cadmium, chromium, copper, nickel, lead, zinc, mercur...

A prevalence study of blood and environmental lead levels was conducted in Galena, Kansas, a heavy metal mining Superfund site. The area is part of an abandoned lead/zinc mining and smelting region often called the Tri-State Mining District (Kansas, Misso...

This paper describes a study of an abandoned lead-zinc tailings impoundment in west-central New Mexico. The method of tailing deposition at this site was an upstreaming peripheral discharge system. Generally, this type of system produces a sedimentary structure that coarsens vertically upward and fines laterally away from the emitters. The use of ...

Two abandoned lead-zinc mine sites, the Nevada Stewart Mine (NSM) and Success Mine, are located within the Coeur d'Alene Mining District, in northern Idaho. An Apatite II� Treatment System (ATS) was implemented at each site to treat metal-laden water, mainly zinc. In the ATS, f...

and abandoned mine features, and determine structural geologic trends in the study area. The GPR data were acquired to identify and locate abandoned mine access and ventilation shafts in areas that were overlain and paleosinkholes), locate abandoned, in-filled and/or caved-in open pit mines; and define areas of probable shallow

Many urban and greenfield environments throughout the United Kingdom are located in regions where mining has occurred. Mining dates back to pre-Roman times and includes metalliferous minerals (such as gold, copper, lead & zinc), bulk minerals (such as sand-stone, limestone, gypsum & halite) and coal, the latter being the most important mineral ...

This study investigated metals of tailings from Tonglvshan mine in Daye and assessed the effect of metal contamination in water and sediment near the tailing reservoir. The concentration of copper, lead, zinc, cadmium, chromium and nickel was measured in deposit samples taken from a profile in an abandoned flotation tailing reservoir, ...

The Virginia gold-pyrite belt, part of the central Virginia volcanic-plutonic belt, hosts numerous abandoned metal mines. The belt extends from about 50 km south of Washington, D.C., for approximately 175 km to the southwest into central Virginia. The rocks that comprise the belt include metamorphosed volcanic and clastic (noncarbonate) sedimentary rocks that were originally ...

Catchment disturbances occur at a range of spatial and temporal scales. Polluted discharge from abandoned metal mines and spoil heaps can persist for centuries after the closure of a mine and leave a legacy of heavy metal contamination in sediment systems. Following the decline of metal mining in Wales during the 20th century, there are over 1 300 ...

Gold, lead, zinc and copper were mined continuously at Captains Flat between 1938 and 1962. The Molonglo River was polluted from a number of sources at the mine site. The mine was finally abandoned in 1962, but it was not until 1974 that a program was instituted to stabilize and rehabilitate the mine workings and waste deposits. Field ...

An abandoned waste impoundment located within a portion of the Bunker Hill Superfund Site constitutes a field research area for studying the feasibility of recovering heavy metals in-situ from unsaturated mine and mill wastes. A prototype in-situ leaching cell has been evaluated using liquid-phase tracer tests and other hydrogeologic tests prior to introducing a lixiviant. The ...

The Federal Bureau of Mines investigated an electrolytic oxidation procedure for extracting lead, zinc, copper, and silver from lead-zinc concentrates. Concentrates slurried in brine were pumped through the anode compartment of electrolytic cells equipped...

A century of heavy metal mining in the western United States has left a legacy of abandoned mines. While large operations have left a visible reminder, smaller one and two-man operations have been overgrown and largely forgotten. We revisited an area of northern Idaho that has not had active mining since at least 1932 and probably since 1910. At three sites along each of 10 ...

In 1997 and 1998 the Department of Geology and Geophysics at the University of Missouri-Rolla conducted high-resolution seismic reflection and ground-penetrating (GPR) surveys for the Missouri Department of Transportation (MoDOT). These geophysical data were acquired in Joplin, Missouri along segments of a proposed bypass in areas that were subject to intense near-surface mining activities ...

Mine tailings in arid and semi-arid environments are barren of vegetation and subject to eolian dispersion and water erosion. Revegetation is a cost-effective strategy to reduce erosion processes and has wide public acceptance. A major cost of revegetation is the addition of amendments, such as compost, to allow plant establishment. In this paper we explore whether arbuscular ...
