How does phytomining plants work? | 5 Answers from …
Phytomining involves cultivating hyperaccumulator plant species on metal-rich mediums to extract valuable metals like gold, thallium, and rare earth elements (REEs) from contaminated sites. The process consists of three main stages: phytoextraction, where plants accumulate metals; enrichment, to increase metal concentration in solid remains; and extraction, to recover metals …

As the United States expands its investment in clean energy technology, the demand for clean energy minerals from viable sources will increase. Plants naturally accumulate metals and other nutrients from the soil in their leaves, stems, and roots. 'Phytomining' could harness this natural activity of plants to accumulate and collect minerals for downstream use in clean energy …

Phytomining: Trends in Plant Science
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 mining practices. …
