This study compares coal mine tailings management strategies using life cycle assessment (LCA) and land-use area metrics methods. Hybrid methods (the Australian indicator set and the ReCiPe method) were used to assess the environmental impacts of tailings management strategies. Several strategies were considered: belt filter press (OPT 1), tailings paste (OPT 2), thickened tailings (OPT 3), and...

One of the challenges in upstream tailings dam projects is to ensure allowable rate deposition pond (i.e., filling rate) while maintaining stability dam. This due fact that an constructed by placing dikes on top previously deposited soft tailings, which could lead a decrease because build-up excess pore water pressure. The main purpose this work investigate effects rates pressure and numerical ...

In Mongolia, combined with the dry and windy climate during spring autumn, exposed sediment of mine tailings pond becomes an additional source anthropogenic windblown dust poses potential threats to surrounding environment human health. this study, we reported on our first attempt derive spatiotemporal distribution originating from Erdenet using a combination ground-based in-situ measurements H...

Tailings ponds Slovinky and Markušovce (Slovakia) belong to the group of high-risk areas threatening human health environment due high concentrations potentially toxic elements. The aim this study was identify iron bacteria living in these extreme environments assess impact selected physicochemical parameters drainage water, flowing from tailings ponds, on dynamics their population.The material...

OBJECTIVE Unreclaimed mine tailings sites are a worldwide problem, with thousands of unvegetated, exposed tailings piles presenting a source of contamination for nearby communities. Tailings disposal sites in arid and semiarid environments are especially subject to eolian dispersion and water erosion. Phytostabilization, the use of plants for in situ stabilization of tailings and metal contamin...

This study was carried out for the purpose of investigating the issue of tailings dams as a potential source of contamination by trace elements in soils at the Sidi Bou Othmane mine in the Marrakech Region, Morocco. Soil samples taken from depths of up to 15 cm and within a radius of 50 m from the tailings dams, were analyzed for Cd, Cu, Pb and Zn using atomic absorption spectrometry. Average c...

Elevated inorganic phosphate (Pi) concentrations in pore water of amended tailings under direct revegetation may cause toxicity in some native woody species but not native forbs or herb species, all of which are key constituents in target native plant communities for phytostabilizing base metal mine tailings. As a result, Pi sorption capacity has been quantified by a conventional batch procedur...

At the active tailings impoundment Carén (surface 22 km) from the porphyry copper mine El Teniente, Chile, initial steps of primary mineral alteration and geochemical changes after deposition were studied. The tailings contained up to 3 vol% sulfides (mainly pyrite). At five points in the tailings impoundment, water samples up to a depth of 4 m were taken from piezometer. Preliminary data showe...
