Market Opportunities: in Sustainable Phytoremediation ...

2019-1-1 · Phytomining. One step beyond phytoremediation, we find phytomining, 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 (Sheoran et al., 2013).

Phytomining: Trends in Plant Science

1998-9-1 · 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…

Phytomining

1998-9-1 · 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% ...

how does phytomining work

2020-11-10 · Phytomining Trends in Plant Science. Phytomining is the production of a crop of a metal by growing highbiomass plants that accumulate high metal concentrations some of these plants are natural hyperaccumulators, environmentally destructive, and in others the property can be induced pioneering experiments in this field might lead to a green alternative to existing, opencast mining practices
