Phytomining researcher Lorna Anguilano, from Brunel University London, has studied hyperaccumulator grasses growing in the orange-coloured sludge coming out of an ancient metal mine in Wales. 'When you cut the grass and look at it, you can see that the leaves are full of metal,' she explains.

Phytomining describes the production of a metal crop by using high-biomass plants, which are plants that produce energy or a usable resource when burned. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bio-ore. ...

Phytomining. Some plants absorb metal compounds (including copper) when they grow. The plants can then be burned and the metal is extracted from the ash. The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel.
