Title Heavy-metal sludges as smelter feedstock Type Journal Article
Year 1994 Publication Engineering and Mining Journal Abbreviated Journal
Volume 195 Issue 9 Pages 25-30
Keywords Metals Mining Groundwater Pollution USA Colorado California Gulch 3 Geology
Abstract Many industries produce a waste-water stream high in heavy metals. Disposal of sludge from these wastewater treatment plants has become increasingly difficult and expensive in the US due to passage of the Resource Conservation and Recovery Act's 'land disposal ban' for hazardous wastes. Innovative methods can be found for dealing with such wastes. For example, in performing a mandated clean-up under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Asarco's California Gulch water-treatment plant in Colorado meets CERCLA clean-up goals while using a waste water treatment sludge as a smelter feedstock, recovering incidental saleable metals, and producing non-hazardous products. In this plant, Asarco treats acidic mine-drainage water having high metal concentrations and uses the waste sludge generated as a lime replacement in lead smelting operations. -Author

Title Metallipitoisten vesien biologisesta kasittelysta Outokummun kaivoksilla. Metal content treated with biological methods at the Outokummun operation Type Journal Article
Year 2000 Publication Vuoriteollisuus = Bergshanteringen Abbreviated Journal
Volume 58 Issue 1 Pages 44-47
Keywords acid mine drainage anaerobic environment bacteria biodegradation environmental analysis Europe filters Finland metals Outokummun Mine peat pollutants pollution reduction Scandinavia sediments sulfate ion Western Europe zinc 22, Environmental geology
Abstract Acid mine drainage (AMD) is one of the most serious environmental problems in the metal-mining industry. AMD is formed by the chemical and bacterial oxidation of sulphide minerals, and it is characterized by low pH values and high sulphate and metals content. The most common method to treat AMD is chemical neutralization. The chemical treatment requires high capital and operating costs and its use is problematic at the closed mines sites. Outokumpu has studied and used sulphate reducing bacteria (SRB) as an alternative method for the treatment of AMD. SRB existing in many natural anaerobic aqueous environments can reduce sulphate to sulphide which precipitates metals as extremely insoluble metal sulphides. Full scale experiments were begun in summer 1995 in the Ruostesuo open pit (depth 46 m) by adding liquid manure as a source of bacteria and press-juice as a growth substrate. The average Zn content of the whole column has decreased from 3,5 mg/l to 0,8 mg/l and below 25 m zinc is 0 mg/l. Similar results have been reached with nickel in the Kotalahti old nickel mine, where bacteria were brought in 1996. We have found that the same bacterial mechanism acts in peat-limestone filters, which Outokumpu has built at several mine sites since 1993.

Title Remediation challenges and opportunities at the Tar Creek Superfund Site, Oklahoma Type Book Chapter
Year 2001 Publication Proceedings of the Annual National Meeting – American Society for Surface Mining and Reclamation, vol.18 Abbreviated Journal
Volume Issue Pages 579-584
Keywords abandoned mines acid mine drainage collapse structures constructed wetlands environmental analysis geologic hazards ground water human ecology Kansas land subsidence lead metals mines Missouri Oklahoma pollution reclamation remediation springs Superfund sites surface water Tar Creek Superfund Site United States water resources wetlands zinc 22, Environmental geology
Abstract The Tar Creek Superfund Site is a portion of the abandoned lead and zinc mining area known as the Tri-State Mining District (OK, KS and MO) and includes over 100 square kilometers of disturbed land surface and contaminated water resources in extreme northeastern Oklahoma. Underground mining from the 1890s through the 1960s degraded over 1000 surface hectares, and left nearly 50 km of tunnels, 165 million tons of processed mine waste materials (chat), 300 hectares of tailings impoundments and over 2600 open shafts and boreholes. Approximately 94 million cubic meters of contaminated water currently exist in underground voids. In 1979, metal-rich waters began to discharge into surface waters from natural springs, bore holes and mine shafts. Six communities are located within the boundaries of the Superfund site. Approximately 70% of the site is Native American owned. Subsidence and surface collapse hazards are of significant concern. The Tar Creek site was listed on the National Priorities List (NPL) in 1983 and currently receives a Hazard Ranking System score of 58.15, making Tar Creek the nation's number one NPL site. A 1993 Indian Health Service study demonstrated that 35% of children had blood lead levels above thresholds dangerous to human health. Recent remediation efforts have focused on excavation and replacement of contaminated residential areas. In January 2000, Governor Frank Keating's Tar Creek Task Force was created to take a “vital leadership role in identifying solutions and resources available to address” the myriad environmental problems. The principle final recommendation was the creation of a massive wetland and wildlife refuge to ecologically address health, safety, environmental, and aesthetic concerns. Additional interim measures included continuing the Task Force and subcommittees; study of mine drainage discharge and chat quality; construction of pilot treatment wetlands; mine shaft plugging; investigations of bioaccumulation issues; establishment of an authority to market and export chat, a local steering committee, and a GIS committee; and development of effective federal, state, tribal, and local partnerships.

Title Experimental diversion of acid mine drainage and the effects on a headwater stream Type Journal Article
Year 1999 Publication Water-Resources Investigations Report Abbreviated Journal
Volume Wri 99-4018-A Issue Pages 123-130
Keywords abandoned mines acid mine drainage algae benthonic taxa biomass biota Colorado experimental studies heavy metals Lake County Colorado Leadville Colorado metals mines pH Plantae pollution remediation Saint Kevin Gulch Colorado tracers United States USGS water zinc
Abstract An experimental diversion of acid mine drainage was set up near an abandoned mine in Saint Kevin Gulch, Colorado. A mass-balance approach using natural tracers was used to estimate flows into Saint Kevin Gulch. The diversion system collected about 85 percent of the mine water during its first year of operation (1994). In the first 2 months after the diversion, benthic algae in an experimental reach (stream reach around which mine drainage was diverted) became more abundant as water quality improved (increase in pH, decrease in zinc concentrations) and substrate quality changed (decrease in rate of metal hydroxide deposition). Further increases in pH to levels above 4.6, however, led to lower algal biomass in subsequent years (1995-97). An increase in deposition of aluminum precipitates at pH greater than 4.6 may account for the suppression of algal biomass. The pH in the experimental reach was lower in 1998 and algal biomass increased. Mine drainage presents a complex, interactive set of stresses on stream ecosystems. These interactions need to be considered in remediation goals and plans.

Title Reclamation and Decontamination of Metalliferous Mining Tailings Type Journal Article
Year 1990 Publication Int. J. Mine Water Abbreviated Journal
Volume 9 Issue 1-4 Pages 223-235
Keywords Britain tailings metals land reclamation environmental damage ground water surface water Wales treatment options
Abstract Parts of Britain have large accumulations of metalliferous tailings derived from mining in the lath, 19th and 20th centuries. These tailings were never subject to land reclamation schemes at the time of mining and are situated very close to water courses. They cause considerable environmental damage in terms of contamination of soils, dust blow and pollution of water courses and groundwater. In some parts of the country mine drainage is a major part of river pollution. In recent years, particularly in Wales, efforts have been made to “clean up” these sites. This has involved using techniques to isolate and contain the spoil, diversion of water courses, and the installation of water treatment facilities and drainage and the establishment of a vegetation cover. Research is also being initiated to investigate ways of decontaminating these metalliferous spoils as an alternative to using covering systems to reclaim them.
