Mine Tailings - an overview | ScienceDirect Topics
Composts have also been added to soils to assist phytoremediation. In mine tailings restoration when clay loam soils were amended with composted biosolids, willows growing in such medium were very effective in phytoextraction of Mn, Cu, and Cd (Boyter et al., 2009).
Effects of chelators on chromium and nickel uptake …
The present study has the following three objectives: (i) investigate biomass production of B. juncea in serpentine-mine tailings under pot experiments; (ii) explore the effects of natural and synthetic chelators on Cr and Ni mobilization in tailings and uptake of metals by B. juncea; and (iii) compare the efficiencies of different chelators in technology-enhanced phytoextraction by B. juncea.

Distribution of potentially toxic elements (PTEs) in ...
15-6-2017 · This study investigated the concentration of potentially toxic elements (PTEs) including Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, V, and Zn in 102 soils (in the Near and Far areas of the mine), 7 tailings, and 60 plant samples (shoots and roots of Artemisia sieberi and Zygophylum species) collected at the Gol-E-Gohar iron ore mine in Iran.
Tailings | SpringerLink
5-6-2010 · Abstract. At nearly every metal mine site, some form of mineral processing occurs, and tailings are being produced. In metal mining, the extracted ore mineral s represent only a small fraction of the whole ore mass; the vast majority of the mined material ends up as tailings.
Distribution and Phytoavailability of Potentially …
The environmental risk of potentially toxic metals in tailing soils is of universal concern. We conducted a 3-month pot experiment to research the distribution and variations of potentially toxic metals (PTMs), and the translocation and accumulation capability of these metals (Cr, Ni, Mn, Cu, Zu) in natural plants for three Fe/Mg tailing soils (serpentine-type, olivine-type and magnetite-type ...

Hence, restoration of mine spoils, tailings and metalliferous soils is a challenging task for the well being of Humans. Synthetic and ... In this review, an update of biotechnological and bioremediation strategies suitable for serpentine soils and mine spoils have been presented in different sections.
Some trace elements in plants from serpentine soils.
Cr concentration ranged from 500 ppm in soils from the boundary of serpentine with sedimentary rock to 6.2% in old mine tailings mine tailings Subject Category: Commodities and Products see more details, but from 10 ppm to 3.4% in the ash ash Subject Category: Miscellaneous see more details of plants.

Herds of cows are impounded with electric fence on mine tailings, metal contaminated soils by providing fodder and water for varying durations. Cows not only stabilize the soil by their hoofs but also enrich soil nutrient status via urination. They also augment microbes to the soil through the dung.

as serpentine mine tailings, is to assess the redox state of Cr (Fandeur et al., 2009). The concentration of Cr(VI) in groundwater in several areas with serpentine soils has been found to exceed the World Health Organization’s limit (50lg/L) for drinking water (Morrison et al., 2009). Despite the presence of a large part of Cr in chromite and Cr-
T HE NATURE OF SERPENTINE ENDEMISM 1
Serpentine race plants grew larger than nonserpentine race plants when grown in serpentine soils ( Fig. 1 ). This result estab-lished serpentine soils as a “potent selective factor” ( Kruckeberg, 1951 ; p. 415) that drives differentiation and local adaptation on par with the selective strength of mine tailings ( Jain and

Cobb Valley The vegetation of the Cobb asbestos mine tailings is exceedingly sparse. On the slopes it is confined to Colobanthus strictus and a dwarf tussock grass (Poa sp.). In the flat areas below the tailings, there is an occasional Nothofagus (Fig.3). The soils of the Dun Mountain Ophiolitic Belt are quite variable but were originally
