Phytomining 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 the nickel (Ni) hyperaccumulator Streptanthus polygaloides and it was found that a yield of 100 kg/ha of sulphur-free .

Finite reserves of copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching. Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing high grade copper ores.

Phytomining could also assist in the sustainable closure of mining sites. Gold can be recovered from the native plants grown during the process of revegetation at the closure sites, thus generating revenue along with rehabilitation (Wilson-Corral et al., 2011). The process of phytomining uses solar energy to generate bio-ore.
