Nickel/cobalt, as well as platinum and palladium metal family members are recovered from soil by growing Brassicaceae plants, specifically Alyssum in soil containing nickel/cobalt as well as other metals. The soil is conditioned by maintaining a low pH, low calcium concentration, and the addition of ammonium fertilizer and chelating agents thereto.Mined out sites, and other degraded lands Mined out sites: Kachchh and Saurashtra are the main regions in Gujarat, which are bestowed with rich mineral resources. Gujarat Mineral Development Corporation (GMDC) is engaged in tapping major mineral resources especially lignite in Panandhro and Mata-Na-Math in western Kachchh region.

X-ray Diffraction (XRD) analysis was carried out on raw samples and on samples heated ex-situ (by a conventional diffractometer) or in-situ (by synchrotron-based diffraction). Raw samples mainly consist of quartz, phyllosilicates, and feldspars with minor amounts of sulfides, sulfates, and Fe, Pb, and Zn carbonates, concentrated in the rhizosphere.Experiments were carried out in Italy on the potential use of the hyperaccumulator Alyssum bertolonii in phytomining of ultramafic soils for Ni. In situ experimental plots at Murlo, Tuscany were fertilized with various regimes during a Z-year period.

The research out of Ireland also posits that phytomining could be used to extract lithium from places less ideal for traditional mining, like low-grade ore bodies and metalliferous soils. "I think, depending on future prices of lithium — the more they increase, the more likely this is to become viable in certain locations," Cleary says.Grath, 1995). In an extensive survey of heavy metal oneering Ni phytomining trials were carried out at concentrations in US agricultural soils, Holmgren et the U.S. Bureau of Mines on a naturally occurring al. (1993) reported a maximum Ni concentration of stand of Streptanthus polygaloides A. Gray, a Ni

Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast mining practices.phytomining. Although the higher return would appear to be possible with use of thiosulfate as the inducing agent, it is our experience that gold extraction does not occur at lower pH values when this reagent is used. If it is desired to use thiosulfate for this purpose, it may be necessary to carry out the additional expense of .

This work was conducted to assess the ability of miners to apply phytomining to tailings, and to carry out a complete operation from planting to final processing of the biomass. This work is a key step towards the eventual uptake of phytomining as a technology to manage the long-term environmental liability of ASGM mine waste.The first field trials involving phytomining were carried out at the US Bureau of the Mines, Reno, Nevada, using the Ni hyperaccumulator Streptanthus polygaloides . The findings of this initial research indicated that a yield of 100 kg/ha of sulfur-free Ni could be produced via phytomining [ 186, 193, 214 ].

Experiments in electrokinetics have been carried out: the soil is subjected to a direct current to promote the movement of ions in the soil. The interaction between phytoremediation and in situ bioremediation (use of micro-organisms, or their enzymes, in the soil) is also being studied.Following earlier proposals3, 4, intensive field trials were designed specifically to study phytomining per se rather than as an adjunct to phytoremediation. The trials were carried out at the US Bureau of Mines (Reno, Nevada)6, 7, 8on a naturally occurring stand of Streptanthus polygaloides (), which is a species known to hyperaccumulate nickel.The soil at the site contained about 0.35% ...

The technique of phytomining involves growing a crop of a metal-hyperaccumulating plant species, harvesting the biomass and burning it to produce a bio-ore. The first phytomining experiments were carried out in California using the Ni-hyperaccumulator Streptanthus polygaloides and it was found that a yield of 100 kg/ha of sulphur-free Ni could ...Abstract. Initial experiments using Mediterranean Ni-hyperaccumulator plants for the purpose of phytomining were carried out in the 1990s. In order to meet commercial phytoextraction requirements, a technology has been developed using hyperaccumulator species with adapted intensive agronomic practices on natural Ni-rich soils.
