Phytomining of gold: A review
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.

GCSE CHEMISTRY
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.

Phytomining
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, …

Phytomining of rare earth elements – A review
Phytomining is widely applied to recover nickel from brownfield land (Chaney, 2018; Jally et al., 2021b). The entire process of this approach for reclaiming noble metals has been introduced recently (Dinh et al., 2022). Nevertheless, little attention has been paid to the procedure or to the prospect of REE phytomining. 2. Phytomining of …
Phytomining: An Innovative Technique for Sustainable
Phytomining is the process to recover those metal/metalloids that are commercially valuable from those sources which otherwise have too low concentration of these valuable metal/metalloids that using conventional mining strategies their economic use is not possible whereas, phytoextraction is utilizing plants to remediate the heavy …
4.1.4 Bioleaching & Phytomining
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 …

Role of bacteria and mycorrhizal fungi in phytomining: status …
The phytomining process consists in the cultivation of hyperaccumulators (preferably native or naturalized noninvasive species) in selected metal-rich substrates, followed by the harvest of the aboveground parts and transformation of the biomass to obtain valuable end products (Kidd et al., 2018, Novo et al., 2017).
Phytoextraction process
Phytoextraction process. Phytoextraction is a subprocess of phytoremediation in which plants remove dangerous elements or compounds from soil or water, most usually heavy metals, metals that have a high density and may be toxic to organisms even at relatively low concentrations. [1] The heavy metals that plants extract are toxic to the plants ...
Phytomining of noble metals – A review
In addition, bacteria and mycorrhizal fungi could be utilized to assist the phytomining process (Alves et al., 2021). Concentrations of NMs in plants under natural soil conditions are typically lower than plants on artificial or amended substrates (see Table 2). To some extent, most of NMs phytomining experiments are applied induced ...
