Mineralogical constraints on the mobility of arsenic in tailings from Zimapan, Hidalgo, Mexico
Arsenic mobility was studied in tailings from Zimapan, a mining zone of Mexico. Primary mineral phases are quartz, calcite, pyrite, pyrrhotite, sphalerite and arsenopyrite. Secondary minerals in oxidised tailings include gypsum, K-jarosite, lepidocrocite, goethite, beudantite and kaolinite. The highest levels of As (up to 3.95 ± 2.29 weight %), Zn (up to 3.26 ± 2.21 weight %) and Pb (up to 0.93 ± ...

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 ...

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 ...

Alleviation of environmental risks associated with severely contaminated mine tailings using amendments: Modeling of trace element speciation, solubility, and plant assssccumulation
Tailings are considered one of the most relevant sources of contamination associated with mining activities. Phytostabilization of mine spoils may need the application of the adequate combination of amendments to facilitate plant establishment and reduce their environmental impact. Two pot experiments were set up to assess the capability of 2 inorganic materials (calcium carbonate and a red ...

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 ...

Biokinetics of Thiobacillus thiooxidans for manganese bioleaching
The waste tailing of metals generated during mining processes is degrading the environment by increasing the soil toxicity, leading to disturbances in the ecosystem. This study was initiated to determine the biokinetics of Thiobacillus thiooxidans for manganese bioleaching in the presence of excess sulphur. In batch studies, the effect of manganese concentration on the leaching efficiency of T. ...

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 ...

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, ...

Quantitative microbial community analysis of three different sulfidic mine tailing dumps generating acid mine drainage
The microbial communities of three different sulfidic and acidic mine waste tailing dumps located in Botswana, Germany, and Sweden were quantitatively analyzed using quantitative real-time PCR (Q-PCR), fluorescence in situ hybridization (FISH), catalyzed reporter deposition-FISH (CARD-FISH), Sybr green II direct counting, and the most probable number (MPN) cultivation technique. Depth profiles of ...

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 ...

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 ...

Tailings Pond Geomembrane Construction Plan and Construction Precautions
The development of the mining industry brings not only a large amount of ore but also many tailings problems to be solved. Yet, tailings stored in tailings ponds often contain a large number of metals, heavy metals, and mineral processing residues. Once environmental pollution occurs, the consequences will be very serious. Thus, anti-seepage measures are usually taken for tailings ponds. The ...
