Phytomining. This process takes advantage of how some plants absorb metals through their roots The plants are grown in areas known to contain metals of interest in the soil; As the plants grow the metals are taken up through the plants vascular system and become concentrated in specific parts such as their shoots and leaves These parts of the plant are harvested, dried and burned

· Phytomining describes the exploitation of sub-economic ore bodies using plants. Would-be phytominers grow a crop of a metal-hyperaccumulating plant species, harvest the biomass and burn it to produce a bio-ore. The first phytomining experiments were carried out by Larry Nicks and Michael Chambers at the US Bureau of Mines, Reno, Nevada using ...

· Abstract. Bioharvesting of metals from high biomass crops grown in soil substrates particularly those associated with sub-economic mineralization is termed phytomining. It is a recent more ...
· Phytomining involves the production of a 'crop' of metals by growing high-biomass hyperaccumulators that accumulate high concentrations of metals (Robinson et al. 1999a).In contrast to simple phytoextraction techniques, the goal of phytomining is primarily to realize the economic benefits and commercialization by comprehensive use of hyperaccumulator plants …
· 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 ...

· The procedure for a phytomining operation comprises a number of standard steps, including: (1) locate a site (mine tailings, mineralized or polluted soils ) with sub-economic levels of the target metal; (2) plant a high biomass yield species with aptitude to accumulate elevated amounts of the target metal (ideally a hyperaccumulator ) and tolerate other coexisting metals; …
· Phytoextraction refers to the removal of contaminants from soils by utilizing plants that uptake the contaminants and transport and concentrate them in the harvestable parts. Phytomining involves the commercial aspect of phytoextraction, wherein hyperaccumulator plants are harvested or mined for minerals by cultivation on metal-rich soils.
