Gold phytoextraction is a commercially available technology, while an international research has shown that phytoextraction will also work for mercury. In the context of this idea, tailings would be contained in 'farming areas' and cropped using phytoextraction technology.
The technique of phytomining involves growing a crop of a metal-hyperaccumulating plant species, harvesting thebiomass and burning it to produce a bio-ore. In the first phytomining experiment, it was found that a yield of 100 kg/ha of sulphur-free Ni could be produced.

This report presents the results of the investigation deriving novel coal mining/preparation systems for clean coal-based fuel. Efforts include the examination of unit operation at each phase of surface mining, underground mining, transportation and preparation processes.
Phytomining for nickel, thallium and gold 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 be produced.
Apr 13, 2013· Money doesn't grow on trees — but gold might. An international team of scientists has found a way to grow and harvest gold from crop plants. Called phytomining, the technique of finding gold ...
Bioassisted phytomining implies targeted use of microorganisms and plants for the selective recovery of the metal. Metals from undissolved compounds are dissolved by applying specially chosen microorganisms and therefore become available to the hyperaccumulating plants. In …
Phytoremediation is a cost-effective plant-based approach of remediation that takes advantage of the ability of plants to concentrate elements and compounds from the environment and to metabolize various molecules in their tissues.
Gold phytomining could be a possible option for tailings management at artisanal and small-scale gold mining (ASGM) locations where plants accumulate residual gold in their above ground biomass. The value of metal recovered from plants could offset some of the costs of environmental management.
Oct 31, 2016· Phytomining is a more specific form of phytoremediation where the purpose of metal removal from soil is economic gain. 2013, Christopher W. N. Anderson, Chapter 5: Hyperaccumulation by Plants, Andrew Hunt, George A. Kraus, James H. Clark (editors), Element Recovery and Sustainability, page 121,

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.
Apr 15, 2013· Called phytomining, the technique uses plants to extract particles of the precious metal from soil. Some plants have the natural ability to take up through their roots and concentrate metals such as nickel, cadmium and zinc in their leaves and …
