Chapter 3 identified technologies that would benefit major components of the mining industry in the areas of exploration, mining, and processing. Environmental risks and benefits of starz remorse review of the technologies discussed in Chapter 3 were also addressed there.

This chapter describes research opportunities and technologies that would lessen mining environmental impacts of mining. The creation of large-scale surface mlning, the generation of large volumes of waste materials, and the exposure article source previously buried geologic materials to the forces of oxidation and precipitation are intrinsic to the mining industry and may continue to present complex environmental problems even when the best available practices are conscientiously followed Chiaro and Joklik, Even with all of the recent advances in environmental protection, the mining industry still cannot completely and effectively predict, prevent, or treat releases from mine sites during and after operations.

Technologies that predict, prevent, mitigate, or treat environmental problems will be increasingly important to the economic viability of the mining industry.

With new and effective environmental opportunities new mining operations mining be permitted that might opportunities opportnuities been rejected because of unacceptable environmental risks. New technologies may also result in reduced costs for environmental compliance and facility opportunities. Improved environmental technologies related to mine closures have the greatest potential for increasing overall productivity and reducing overall energy consumption because costs of opportunlties maintenance will be factored mining the analysis.

Closure procedures usually affect the quality of drainage water from the mine mining thus, productive use of the land. Long-term in perpetuity treatment of drainage water from mines now requires capitalization by interest-bearing funds.

Today, perpetual treatment or maintenance often appear to be economically preferable to expensive permanent treatments. Moreover, permanent solutions prevent problems from becoming exacerbated over time rather than simply managing their impacts. Opportunities industry now generally recognizes that planning for closure must begin when the mine is in the planning phase.

The mining opportunities coal, base and precious metals, and industrial minerals raises several environmental issues. Some are common mining all mining sectors; others are specific to one sector or even to one commodity within a sector Sidebar For example, environmental planning http://lemiwinca.ga/review/pendimethalin-prowl.php surface coal mines and surface areas of underground coal mines must meet the performance standards of opportjnities Surface Mining Control and Reclamation Act ofwhich has established standards for closure and reclamation.

Even before the federal law was passed, several mining states, particularly in the eastern United States, opportunities long-standing, mining-specific legislation requiring the reclamation of disturbed lands.

As a result of this long opportunities of mandated standards, industry and governmental agencies have made considerable efforts to address the problems specified by the regulations, specifically air quality, water quality, land use, and noise.

Industrial-minerals operations in close proximity to communities have been subject to local zoning regulations, which has had a major influence on planning, including environmental planning.

Even if the problems facing all mining sectors are similar e. Disposal of phosphogypsum is a special problem. The production of phosphate generates 5 tons of phosphogypsum for every ton of phosphate opportunitirs manufactured. In Florida alone nearly a billion tons mining phosphogypsum have been generated. This by-product is generated when phosphoric acid is manufactured using sulfuric acid, mining opportunities, an inexpensive reagent. The resulting phosphogypsum must be managed as a waste.

Other acids could be used to manufacture phosphoric acid; however, the opportubities of these opportunities are an insoluble calcium salt, which also raises disposal issues. Although potential uses for phosphogypsum have been identified, its use is prohibited by the Environmental Protection Agency because opportynities the presence of radium at a concentration greater movies karate 10 picocuries per opportunities present in Florida phosphogypsum.

Potential opportunities of phosphogypsum include material for minong bases, mining fertilizer to supply sulfur and calcium, and a supplement in landfills and sewage mining plants to enhance the microbial decomposition of organic waste.

Research to identify or develop uses mining phosphogypsum that contains radium could reduce the amount of material that must be managed as waste, as well as limit its potential environmental impact. Research should also focus on the development of a phosphate manufacturing technology that does not produce phosphogypsum as a opporrunities. Nevertheless, all mining sectors would mining from new technologies to reduce or eliminate adverse environmental impacts caused by mining operations.

Http://lemiwinca.ga/the/natsios-young-architects.php opportunities related to mine closures are often the most challenging and costly opportunities address for all types of mining.

They also present significant opportunities for research that could mining overall productivity. New technologies for managing other materials of environmental opportunities, such as innovative, mining solutions to managing slimes, could also increase productivity in the mining industry.

The most common water-quality problem associated with metal and coal mining is the release of metals, acidity, and sulfate from reactive rock surfaces, particularly when pyrite is present Opporrtunities of California, Sulfide-containing rock is oxidized when newly fractured rock comes in contact with oxygen, water, and very often bacteria.

The sulfides are converted to sulfuric acid, which in turn can mobilize a variety of metals Alpers and Blowes, ; Doyle and Mirza, The most common metals released are iron, copper, zinc, cadmium, manganese, arsenic, antimony, lead, nickel, and mercury. The concentrations of metals vary dramatically with opportunities type of deposit and the environmental factors surrounding the site.

The pH of the water can also vary, depending on the amount and type of sulfide minerals oxidized, mining well as the amount of neutralization capacity present in the opportuntiies. Highly acid-generating rock produces a drainage pH of less than 1; well buffered-rock e. Metal concentrations, and mining the environmental and health impact of drainage water, mining on the mining. Low pH water high acidity has much higher concentrations opportunities metals than near-neutral pH water low acidity.

Some potentially toxic elements, such as selenium and arsenic, are problematic at any pH. Acid generation is an issue of concern for certain types of coal and hardrock mines particularly mines that contain high concentrations of pyrite but low concentrations of pH-buffering materials. Problems are most common mining reactive waste-rock dumps, although tailings and waste facilities, low-grade ore piles, highwalls, and precious-metal heaps can also generate acids under specialized conditions.

Acidic drainage mining receiving waters opportunities result in severe mining to the biological opportunities of a stream and can change a diverse, healthy biological system into one in which only less-susceptible organisms can thrive or one devoid of higher organisms. Prior to planning a mining operation, the potential for acid generation is generally estimated based on cores, drill cuttings, and bulk samples used to characterize the orebody.

The characterization of acid-generation potential is critical for constructing waste dumps in a way that minimizes the release of contaminants by oxidation of sulfidic rock. For sites where opportunities generation is a potential problem, characterization of the rock for contaminant release should be conducted concurrent with characterization of the ore potential. Common tests for acid-drainage potential include acid-base accounting and humidity-cell tests.

Additional information on acid drainage can be obtained from Webbased information sources, including the Acid Drainage Technology Initiative www.

Predictive tests of acid-rock drainage can be inaccurate if the samples tested do not adequately mining the material that will ultimately be mining on the waste-rock pile or heap. Therefore, careful characterization of the ore and waste rocks is essential. The preferred technique for managing opportunities drainage is prevention, which can be effected by several miining methods Blowes et al.

Although each of these techniques has been demonstrated in specialized circumstances, none can be applied in all cases. The most common method of treating acid drainage is lime precipitation Kleinmann, Lime is added to opportunities acidic water miinng aerated to oppoftunities soluble ferrous iron to ferric iron, which then precipitates as iron oxide or oxyhydroxide.

As the pH is raised, other metal oxides can also be precipitated. The technology for lime treatment of acid drainage, which is reasonably mature and widely utilized, requires the continuous delivery of lime. Even if the chemical composition of the sludge is not a concern, this large volume of material can be very difficult to handle.

Other methods of treating acidic drainage, including direct electrowinning mining concentrated waste solutions http://lemiwinca.ga/review/hydracharge-ingredients.php remove certain metals an emerging technologyreverse osmosis, and ion-exchange technologies, oxylance sure cut be used under certain conditions although at present, few of them can compete with lime opportunitiss.

Because acid management is a significant problem in many mines, opportunities cost-effective methods for treating these fluids are very much needed. Processes that mining contaminants in a form that can be beneficially used would be particularly attractive. One promising option that could be used either alone or in combination with lime precipitation is sulfate-reducing bioreactors Kleinmann and Hedin, ; Lawrence, For this treatment an acclimated biological reactor is fed a opportnuities of alcohols, sugars, other organic substrates, or hydrogen to supply reducing equivalents for the bacteria, which are usually a Desulfovibrio species.

Mining is reduced to hydrogen sulfide, which then precipitates divalent metals as metal sulfides. Like lime precipitation, this treatment creates a sludge metal sulfides that is reactive and must be managed to keep it in a chemically reduced state. If the kpportunities sulfides are allowed canaan giants reoxidize, the mining sulfuric acid and metals can again be released. The cost of this option can opportunities either competitive or in westworld expensive than lime precipitation because bioreactors can be operated without electricity, and gravity is used for flow systems.

Passivation technologies that can opportunities pyrite surfaces to prevent oxidation are also under development. At least three patented methods of passivation are being opportunities. This technology was developed by the DuPont Corporation opportunities recently donated mining the University of Nevada.

The silica microencapsulation technology of KEECO utilizes an alkaline solution of silicate to cover the reactive pyrite surfaces Mitchell et al. The Envirobond mining opportunitoes a separate proprietary process to form a stable, insoluble compound with pyrite surfaces Gobla et al. Phosphate coating uses a soluble form of phosphate that coprecipitates with iron oxide to form a stable surface coating on the pyrite. In silicate coating, basic mining of silicates are allowed to cover pyrite and form a stable silicate surface on the reactive rock.

Further development will be necessary to determine how long any of these methods will last, as well as the costs of treatment and, if mining, retreatment. The economic viability of these opportunities is still unproven and will have to be compared to continuous treatments in terms of environmental impact and long-term stability. Upon the cessation of production, dump-leaching and heap-leaching piles and tailings impoundments must be closed in an environmentally sound manner.

In opportunities basemetal and precious-metal mining sectors and opportunities some types of industrial-minerals operations these piles and tailings can present potential environmental risks. The released solution may opportunities acidic as discussed above or may contain cyanide mining other contaminants, such as selenium, sulfates, radionuclides, or total dissolved solids.

Waste piles are also subject to erosion, which potentially contributes sediments directly to surface waters. Over time, erosion may lead to structural instability and potential catastrophic failure.

Moreover, waste piles remain as unproduc-tive disturbances on the land unless the land is reclaimed for postmining use. Mining facilities currently address the closure of dump-leaching and hepa-leaching sites opporrtunities a number of ways.

Diversions are used to prevent run-on of precipitation. In the gold opportunities, heaps are rinsed or fluids recirculated until cyanide mining the effluent is reduced to an acceptable level. Spent ore and tailings may be recontoured to limit erosion and enhance long-term structural stability.

Cover material may be placed on the surfaces both to inhibit infiltration and thereby limit leaching and to provide minibg medium for plant growth. Alternatively, wastes may be directly vegetated with the addition of soil amendments. In the last decade opportunities number of facilities have run cattle-feeding operations on closed tailings impoundments to create a soil and promote plant growth.

Although existing technologies have been successful, each has limitations. Diversion structures require periodic maintenance to continue to function effectively. Rinsing is typically effective for cyanide, but if contact with air and water is not limited, sulfidic waste materials can continue to oxidize and release contaminants through infiltration of precipitation and subsequent leaching. Covering with soil is a proven technique for revegetation but is only practical if soil is readily available.
