Phytoremediation of inorganics is comprised of technologies to protect the environment from contaminated soils. This broad group of technologies includes phytoextraction (removal from soil), phytomining (accumulating economic metal value in plant biomass) and phytostabilization (limiting plant metals and soil metal uptake and/or …
phytomining has an environmental impact like agriculture or agroforestry and it does not require mine site rehabilitation at the end of life (Harris et al. 2009). Phytomining might also generate renewable energy from the incin-eration of plant biomass before smelting or hydrometallurgical refining (Anderson et al. 1999).
This concept of mining metals using plants is called phytomining. Plants that absorb metal compounds through their roots could be planted in contaminated soils, then harvested and the metals …
Phytomining is an innovative application of phytoremediation process that involves accumulators or hyperaccumulator plants grown in polluted soils, being able to accumulate high concentration of metals in their tissues, where from valuable heavy metals (e.g. nickel, cobalt, copper, zinc) will be recovered by biomass processing. This technology can be …
Producing metal by growing plants, or phytomining, has long been tipped as an alternative, environmentally-sustainable way to reshape – if not replace – the mining …
The saga of the 'long and winding road' for the development of phytomining and now agromining continues even in the face of the current low world price for base metals. The story has been well told in a New Scientist article by Moskvitch ( 2014) and is also summarized in the stylized time-line illustrated in Fig. 2.

The first field trials on Ni phytomining in 1994 were based at the US Bureau of Mines, Reno, Nevada (Nicks and Chambers, 1995, Nicks and Chambers, 1998) and used a naturally occurring stand of Streptanthus polygaloides (Fig. 1), a known Ni-hyperaccumulator (Reeves et al., 1981, Nicks and Chambers, 1998).The soil contained …
In the tropical context, phytomining will take place in mining leases funded by mining companies, whereas agromining works via arrangements with farmers and landowners to manage crop production and harvest, with payment on the basis of the Ni contained in the harvested crop. 3 Suitable soils for implementation.
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 is a newly emerged technology in which hyperaccumulator plant species are cultivated on metal-rich medium for commercial metal recovery. The technology is instrumental in the recovery of costly metals such as gold and thallium. It attracts …
Phytomining is defined as the uptake and pre-concentration of bioavailable metal species from the environment into the plant biomass in a natural way. Phytomining
Producing metal by growing plants, or phytomining, has long been tipped as an alternative, environmentally-sustainable way to reshape – if not replace – the mining industry. Of 320,000 ...
In 2024, scientists are figuring out how to mine with plants, known as phytomining. Of the 350,000 known plant species, just 750 are "hyperaccumulators" …
Learners use key words to complete sentences to describe phytomining. This activity is available as both a printable worksheet and an interactive worksheet. Learners will meet learning objective 1 and partially meet learning objectives 3 and 4. Sequencing activity. Learners rearrange the sentences to describe the process of phytomining.
In the future, when supplies of higher grade ores have run out, metals might be extracted by burning the plants to produce ash. The ash would contain a higher concentration of metal than the soil ...
Abstract. Bioharvesting of metals from high biomass crops grown in soil substrates particularly those associated with sub-economic mineralization is termed phytomining. It is a recent more advanced technology of phytoremediation to produce low volume, sulphide-free 'bio-ore', which can either be safely disposed of or, if the target …
Phytomining is an innovative way to recover metals from soils, and it has attracted more and more attention in recent decades (Li et al., 2020; Robinson and Anderson, 2021; van der Ent et al., 2021). In the economic aspect, NMs have been suggested as potential candidates for phytomining because of their high value.

Phytomining (PM) is defined as the process of using plants capable of bio-extracting metals from soil in order to explore them economically. This relatively new, innovative method has been gathering significant attention in both the academic and commercial domains. Conventional mining methods are often economically unviable …

Phytomining is one of the potentially creative and cheap sustainable techniques for choosy recovery of important metal/metalloids from various inferior …
Highlights Gold phytomining can be applied to mineralized soils and gold mining waste. Literature evidence supports the technical validity of the technology. Chemical use is the greatest drawback to gold phytomining but this can be managed. Production costs, gold yield and value support the economic viability of the system. Operations …
‣ ca. 2020, phytomining enterprises began to appear in Europe. ‣ Mining companies like became interested in phytomining to restore the waste sites and secondary mining. ‣ Only very recently, there are new phytomining companies formed in the US, but essentially they are 'paper companies' trying to raise funds.
Phytomining involves the natural uptake and preconcentration of bioavailable metal species from the contaminated fields into the plant tissues. It is a potential economic exploitation of the ...
Phytomining is a technique that involves growing plants in soil that contains metal ions. These plants absorb the metal ions through their roots and concentrate them in their shoots and leaves. The metal-rich plant material is then harvested and burned to produce metal-rich ash, which is further processed to extract the metals.
Phytomining can provide new opportunities to increase the geographic scope of mining across larger areas despite lower concentrations. This could become very useful on lands where the environmental risk or indigenous sovereignty make traditional mining prohibitive. Assuming low-grade ore deposits become increasingly important for …
Phytomining for metals other than nickel. There are practical limits to phytomining[13]. The main variables that control its economic feasibility are: the metal price, the plant biomass, and the highest achievable metal content of the plant (Table 2). Metal values range from about $15 000 000 t − 1 for platinum to about $600 t − 1 for lead.
