Assessment of the phytoremediation potential for Pb, Zn and Cu of indigenous plants growing in a gold mining area in Tanzania . ... Phytoaccumulation, Environmental Sciences, Miljövetenskap ...
Phytomining of gold is a 'green' approach to the environmentally sensitive and energy intensive practice of mining, involving the use of selective plants to extract valuable metals from both solid and liquid substrates. It is a viable alternative or supplementary to conventional mining methods of low grade gold ore bodies' soil.
For example mining occurred at New Union Gold Mine, south Africa until the 1990s when the gold bearing ores were depleted (Ward and Wilson 1998). During the processing of gold, mercury and cyanide were used and the mine wastes were ... coefficient is a better tool to evaluate the phytoaccumulation potential of plants and grasses. this
Modern industrial gold mining destroys landscapes and creates huge amounts of toxic waste. Due to the use of dirty practices such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of toxic waste for every 0.333-ounce gold ring. The waste, usually a gray liquid sludge, is laden with deadly cyanide and toxic ...

Suatu metode lahan basah buatan terpadu diterapkan pada penelitian remediasi lingkungan dengan menggunakan tanaman Phragmites australis dan mikroba pada kompos untuk mengurangi konsentrasi merkuri (Hg) pada air limbah. Air limbah yang digunakan pada penelitian terdiri dari limbah asli tambang emas rakyat Pongkor dengan konsentrasi 27 ppb dan limbah buatan dengan konsentrasi 30 ppb, 60 …
Performance of rose scented geranium (Pelargonium graveolens) in heavy metal polluted soil vis-à-vis phytoaccumulation of metals. Sukhmal Chand, Geetu Singh, Rajkumari & D.D. Patra. ... Beneficial use of industrial by-products for phytoremediation of an arsenic-rich soil from a gold mining area.
The São Domingos mine (abandoned in 1966) located in south-east Portugal is also included in this study. This is one of the historical mining centres, known for its activity since pre-Roman times, with extraction of gold, silver and copper though copper production was the highlight. A summary of soil trace element data is presented in Table 4 ...
Mining is among the activities that alter soil composition the most, which causes visible ground damage by open-pit mines, mine waste tips, tailings ponds and other mine facilities. The main goal of this work was to assess the effect of earthworm on the microorganism growth in mercury polluted soil exposed during the mining activities in the ...
Phytoremediation of soil has attracted much attention in recent years due to its multiple advantages such as maintaining the biological activity and physical structure of soils, being potentially inexpensive and visually unobtrusive, and providing the possibility of biorecovery of metals. Identification of native species for phytoremediation is a key to the success of the method.
technology, but up to now, only a limited number of plants have been found to have the phytoaccumulation ability, and ... These soils were polluted with heavy metals after gold mining. It …
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well ...
Results suggest a facilitation role of native and pollution adapted AMF on Hg phytoaccumulation. E.g., E. polymnioides increased Hg accumulation when growing with greater AMF colonization. We concluded that E. polymnioides is a good candidate for the design of microbe-assisted strategies for Hg remediation at gold mining areas.

Gold mining stocks pulled back a bit after yesterday's upside move as gold failed to gain more upside momentum after a successful test of the resistance at $1865.
The growth of artisan gold mining in Ghana is negatively affecting the mined soil and plant growth in areas where these activities take place. Various mechanisms are being used to remediate these mined soils. This study looked at using selected plant species in phytoremediating the
Mining activities generate a large amount of solid waste and acid drains that contain heavy metals in high concentrations. In wastewater of gold mines from Southern Ecuador (Portovelo), arsenic concentrations between 4.8 and 27.5 μ g/L have been detected. In this context, the objective of this study is to prepare a technosol, which was used in the capture of arsenic dissolved in the acid drains.

In the recent time, phytoremediation became an emerging remediation technology due to its low costs and high sustainability. For the remediation of a contaminated mining site with low to medium heavy metal (HM) concentrations, experiments for the phytoextraction and growth behaviour of Helianthus tuberosus were performed. pH and HM concentrations were identified as crucial factors for plant ...
