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 aim of this work is to investigate the causes El Descargador tailings dam failure, at mine district Cartagena–La Unión (SE Spain), in October 1963. Dam stability back analyses have been carried out by applying a geotechnical and geophysical approach. failure occurred form several landslides five different points along structure. rise pore pressure steeped slopes tails, scaling up 40° some s...

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...

Abstract By the example of one mining tailings dams on Kola Peninsula functionality its guarding dam was investigated. For this purpose, a hydrogeomechanical 3D model created, reflecting geometrical dimensions, geomechanical and hydraulic conditions operation. Using Plaxis 3D, calculations were made for 16 variants increase coefficient transverse filtration water through body. The dependences s...

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 author describes the global patterns of geodynamics-related accidents at tailings ponds mining and processing plants. Based on statistical analysis causes such accidents, it is concluded necessity anticipatory mathematico-cartographic modeling geodynamic possible after-effects dams their design stage. allows integrating computation, spatial representation analysis, as well ensures reliable ...
