The future of the red metal: discards, energy, water, residues, and depletion
Estimates for mine tailings, smelter slag, mine overburden, stock buildup, loss of copper discards to the landfills, and energy and water use requirements have been presented based upon scenario analysis results of three alternative copper futures. The resource availability concerns emerge to be the most critical. Globally, the copper resource availability barrier might potentially emerge during ...

Dust from Mine Tailings Causes These 3 Problems
Dust from mine tailings is a significant concern for communities surrounding inactive and active mines. The problems caused by dust affect people and the environment in a number of ways, which is why it is important to control the dust from mine tailings quickly and effectively. What Are Mine Tailings? Mining operations mine for minerals of interest, such as lead, zinc, copper, silver, and ...

Suitability of Wastes from Olive-Oil Industry for Initial Reclamation of a Pb/Zn Mine Tailing
An incubation experiment was conducted to evaluate the ameliorating role of two organic amendments—olive-mill solid wastes and compost from olive-mill solid wastes- in the ecological reclamation of a lead/Zn-mine tailing collected in southern Spain. Four enzymatic activities (dehydrogenase, β,-glucosidase, urease and phosphatase) and soluble and AB-DTPA extractable Pb and Zn and were ...

What is the most valuable dust control solution for mine tailings?
Mine tailings are highly vulnerable to wind erosion and dust, which creates serious environmental and safety concerns. Dust control for mine tailings must be cost-efficient, effective, and reliable. Acrylic polymer products, such as Envirotac dust control products, reduce dust levels of haul roads and mine tailings and deliver clients the maximum value of their investment. Tailing Lead to ...

Acid production potentials of massive sulfide minerals and lead–zinc mine tailings: a medium-term study
Weathering of sulfide minerals is a principal source of acid generation. To determine acid-forming potentials of sulfide-bearing materials, two basic approaches named static and kinetic tests are available. Static tests are short-term, and easily undertaken within a few days and in a laboratory. In contrast, kinetic tests are long-term procedures and mostly carried out on site. In this study, ...

VSEP filters mine tailing pond effluent with no pre-treatment required
New Logic International installed its Vibratory Shear Enhanced Processing (VSEP) system in March, 1998 at a major California rare earth mining and manufacturing facility. The VSEP is used for treatment of mine tailing pond effluent at this facility with no pretreatment required. The VSEP system uses nanofiltration followed by ultrafiltration membrane modules and is able to treat the mine tailing ...

ArmorMax® Chosen in Milltown reservoir diversion channel stabilization project for state of Montana case study
PROJECT SUMMARY Over 100 years of deposited mine tailings prompted the Montana DEQ and U.S. EPA to embark on a major initiative to breach the Milltown Reservoir Dam and clean up contaminated sediments. But maintaining the flow of the Blackfoot and Clark Fork Rivers called for a potentially expensive diversion channel. Incorporating the AR-MORMAX® ARVS in the upper cross section to protect ...

Importance of Dust Control Polymer For Mine Tailings
While separating the minerals from the ore, the residue is a concern for the environment. Tailings are the leftover material after the process. Mine tailings are toxic therefore are recommended to be kept away from the environment. While leaching, the chances are high that the toxic material might get into the water. It pollutes the streams and leads to destructive environmental conditions. The ...

Release of metals and arsenic from various mine tailings by Eriophorum angustifolium
Abstract Previous investigations have found that plants grown on sulphide-rich mine tailings have phytostabilising effects on acid mine drainage (AMD) by decreasing the pH and preventing the release of metals. The possibility of similar effects on tailings containing other minerals was investigated here. The aim was to examine the effects of Eriophorum angustifolium on four water-covered mine ...

Phosphate Mine Tailings - Case Study
THE CHALLENGE A typical phosphate mining operation can produce between 180,000 and 225,000 gallons per minute of fine phosphatic clay tailings. This material has a solids concentration of between 2% and 7% on a dry-solids basis. Currently, ponds and lagoons are used for settling and clarification of these materials. Many of these polishing ponds are approximately 200 to 300 acres in size, and ...

Analyses of trace elements on quartz surfaces in sulfidic mine tailings from Kristineberg (Sweden) a few years after remediation
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been applied to determine the elemental composition of the surface layer, as well as of the first interior layer, of quartz grains from the mine tailings from Kristineberg (northern Sweden) in order to determine concentration gradients between these two layers. The quartz grains were collected from the oxidized and ...

Geochemical modelling of the evolution and fate of metal pollutants arising from an abandoned gold mine tailings facility in Johannesburg
Analytical techniques were combined with geochemical modelling to study the release mechanisms of pollutants from an abandoned gold mining tailings storage facility near Johannesburg. Inverse modelling of sampled tailings pond water and experimental single extractions using various solutions indicated which combination of naturally occurring leaching solutions were likely to give rise to the ...

US Military’s First Choice for Dust Control Solutions – Rhino Snot (Envirotac II)
Home soil or foreign, whenever the US Military is in need of a dust control job, they call EP&A Envirotac Inc. without a second thought. The US Military first came to know about Envirotac’s dust control products during its Afghanistan mission in 2002, where it used Envirotac II polymer for helicopter landing site and airfields in the Camp Rhino. This is also where Envirotac II received ...

American Standard Double-side Smooth GM13 HDPE Geomembrane For Gold Mine Tailing Treatment
Current Status Of Gold Mine Tailings Pollution There are one hundred gold mine tailings ponds in Zhaoyuan City, most of which are valley-shaped, hillside-shaped and flat. Most of them have been covered with soil for farming, some are in use, and some are not covered with soil, and some are pressed with a layer. Thin soil is easy to form a second dust hazard and still affect the surrounding ...

Migration and speciation of heavy metal in salinized mine tailings affected by iron mining
The negative effects of heavy metals have aroused much attention due to their high toxicity to human beings. Migration and transformation trend of heavy metals have a close relationship with soil safety. Researching on migration and transformation of heavy metals in tailings can provide a reliable basis for pollution management and ecosystem restoration. Heavy metal speciation plays an ...

Root penetration through sealing layers at mine deposit sites
To prevent acid mine drainage arising from oxygen and water penetration of sulphide-rich mine tailings, the tailings are covered with layers of dry sealing material. Plant roots have a great ability to penetrate dense materials, and if the roots are able to penetrate the sealing layer of a tailings deposit, its oxygen-shielding properties could be reduced. The objective of this study was to ...

Optimising the rehabilitation of polluted mine tailings and water by an organic medium passive acid mine drainage treatment in South Africa
Up to the present polluted Acid Mine Drainage (AMD) also known as Acid Rock Drainage (ARD) from South Africa's gold mines was treated by the precipitation of heavy metals with lime and expensive caustic soda where the residues accumulate in the treated water. This water then is dispersed into wetlands for natural remediation. The environmental damage to soil is irreversible and can sterilise soil ...
