·A mine tailing site undergoing ecological reha bilitation Pioneer plants are growing in the tailing impoundment area Tailings are residue minerals left behind from min ing and processing ores and their sustainable reha bilitation is one of the most costly and dicult chal lenges facing the global mining industry Tailings are
·Microorganisms and/or plants can be used for bioremediation to render hazardous materials innocuous or less dangerous in an eco friendly manner and at a very low cost process Azubuike et al 2016; Shah 2014; Ojuederie and Babalola 2017 However bioavailable nitrogen N content of mine tailings limits the microbial and plant growth which
·Most mining sites are incapable of supporting phosphorus and potassium N P K were deficient in overburden dumps This makes it unable to support plant growth unless supplied with right in Ghana by illegal small scale mining activities The illegal small scale mining creates tailings dams containing toxic chemicals such as
·Total mercury THg concentrations in plants from uncontaminated control sites are usually less than μg/g Lindqvist et al 1991 but are abnormally high in plants growing in abandoned Hg mining regions Higueras et al 2006; Zhao et al 2014; Fernández Martínez et al 2015 Therefore under such conditions plants may act as a
·The Louis Moore Mine is an abandoned underground mine situated in the Ka Mavalane village about 10 km north of the town of Giyani along the road leading to Malamulele in Limpopo Province Tailings constitute the only significant mine residue at the site This study assesses the environmental
·The Old Tailings Dam OTD located at the Savage River mine western Tasmania contains 38 million tonnes of pyritic tailings deposited from 1967 to 1982 and is actively [Show full abstract
·The rhizosphere is an important interface for soil plant interaction and a significant zone for the uptake and removal of heavy metals from soils This study assesses the level of heavy metals contamination in the rhizosphere of plants growing at a decommissioned tailings dam in Ghana Concentrations of heavy metals [Arsenic Cadmium Copper Iron
One approach to minimize or eliminate these processes is to establish a permanent vegetation cover on tailings piles Here we report a revegetation trial conducted at a moderately impacted mine tailings site in southern Arizona A salt and drought tolerant plant four wing saltbush [Atriplex canescens Pursh Nutt ] was chosen for the trial A
·Mine tailings MTs are the materials dumped on a mining site after mineral extraction containing scattered traces of residual minerals dug up soils and a disturbed ecosystem Abandoned and untreated MT can pose threats to the surrounding ecosystem due to the presence of various primary and secondary toxic components such as organic substances
·In order to investigate the effects of biosolids and plants in soil physicochemical conditions of iron mine soils we conducted two plant growth trials Trial 1 consisted of tailings that received biosolids and topsoil TUSB mix while in trial 2 tailings received biosolids only TB mix
·Furthermore the revegetation in mine tailings enhances the associated heterotrophic microbial consortia which may in turn promote plant growth and are of critical importance to the ecological functioning of an ecosystem Glick 2003; Mendez et al 2007; Mummey et al 2002; Huang et al 2012 Phytostabilization as a rehabilitating boon
·Strip mining operations greatly disturb soil vegetation and landscape elements causing many ecological and environmental problems Establishment of vegetation is a critical step in achieving the goal of ecosystem restoration in mining areas At the Shouyun Iron Ore Mine in suburban Beijing China we investigated selective vegetation and soil traits on a tailings
·Moreover the number of catastrophic dam failures from mine tailings has increased globally Phytoremediation could be combined with phytomining to revegetate and restore often denuded environments reduce dam breeching and recover valuable metals These pathways could be engineered into fast growing plants that can be harvested to
