Over the past half century, a surprising number of major pollution incidents occurred due to tailings dam failures. Most previous studies of such incidents comprised forensic analyses of environmental impacts after a tailings dam failure, with few considering the combined pollution risk before incidents occur at a watershed-scale. We therefore propose Watershed-scale Tailings-pond Pollution Ris...

This paper presents the methodology developed by the association of Mineração Rio do Norte S.A. with Embrapa/Agrobiologia and the Soil Department of Federal University of Viçosa to promote revegetation of tailings ponds from bauxite mining in Porto Trombetas, Para State, Brazil. The tailings have a fine texture (77% clay), are low in nutrients, have low pH (4.5) and high Pfixation capacity. Thi...

The effects of the disposal of copper mine tailings on the littoral meiofaunal assemblages of the Chañaral area of northern Chile were studied. Of the metals data collected, only in the case of copper was there a clear association with the tailings distribution in both the seawater and porewater samples, and it is assumed that the tailings on the beaches was the source of copper in the adjacent...

During the Late Permian period, coal from Jiashun Mine in Xingren City, Guizhou Province, China, is characterized by a high sulfur (5.84%) and lithium (Li) (94.5 μg/g) content. Lithium critical metal context of global energy transition. Considering importance environmental protection resource utilization, mode occurrence distribution trace elements different preparation products were investigat...

A pot experiment was conducted to investigate the feasibility of growing energy sugarcane (Saccharum spp.) in three different metal mine tailings (Cu, Sn and Pb/Zn tailings) amended with uncontaminated soil at different mixing ratios. The results indicated that sugarcane was highly tolerant to tailing environments. Amendments of 20% soil to Sn tailings and 30% soil to Cu tailings could increase...

We tested the efTect oC the addition oC biosolids combined with a native rnycorrhizal inoculum (Arbuscular Mycorrhizal Fungi [AMF]) 00 growth oC a native Australian grass, and 00 trace element stabilization oC sulphidic gold mine tailings. A glasshouse trial was established 00 four substrates: tailings (T); tailings with a layer oC 5 cm topsoil (TS); tailings amended with 100 dry t ha-1 biosoli...

The Athabasca oil sands deposit is the largest reservoir of crude bitumen in the world. Recently, the soaring demand for oil and the availability of modern bitumen extraction technology have heightened exploitation of this reservoir and the potential unintended consequences of pollution in the Athabasca River. The main objective of the present study was to evaluate the potential impacts of oil ...

Here we describe microarray expression data (raw and normalized), experimental metadata, and gene-level data with expression statistics from Saccharomyces cerevisiae exposed to simulated asbestos mine drainage from the Vermont Asbestos Group (VAG) Mine on Belvidere Mountain in northern Vermont, USA. For nearly 100 years (between the late 1890s and 1993), chrysotile asbestos fibers were extracte...

At the Bonfim mine, cyanide processing used to extract gold from abandoned tailings represents an important environmental concern. In order to evaluate cyanide concentrations, twenty samples of sediments of the main streams crossing the mine site, and ten samples of the five mainly tailings were analyzed for total cyanide. Cyanide was found in two samples of tailings (0.83 and 1.44mg/Kg of tota...
