Phytomining of gold is a 'green' approach to the environmentally sensitive and energy intensive practice of mining, involving the use of selective plants to extract valuable metals from both solid and liquid substrates. It is a viable alternative or supplementary to conventional mining methods of low grade gold ore bodies' soil.

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 …

Acid drainage (AD) is a biogeochemical process occurring with the oxidation of sulfide-bearing minerals, which generates an acidic solution enriched with sulfate, iron, aluminum, other salts and various heavy metals ( Jacobs et al., 2014 ). Acid drainage is both geogenic and anthropogenic in origin, yet greater concern lies in AD resulting from ...

As a non-biodegradable substance, these minerals bio-accumulate to toxic levels due to their persistence and leachability of their soluble forms in soil (Du Preez et al., 2017). In 1997 about 471 million metric tons of mine waste were generated, 47,000 ha of land was used as slim and waste rock dump and 200,000 ha were transformed for mining ...

It is generally accepted that phytomining is greener than conventional mining practices. In environments with metal-contaminated soil, phytominers can re-collect metal pollutants from the soil, thereby restoring the soil to health. Still, growing mass amounts of plants also takes a toll on the land used for cultivation.

Throughout the 1990s and 2000s, scientists further investigated the feasibility of nickel phytomining in Brazil, South Africa, the USA and Mexico. Several patents were taken out on nickel phytomining between 1998 and 2004. However, nickel phytomining is still not in operation as a commercially viable activity anywhere in the world.

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, …

Chaney was the first to propose the use of metal hyperaccumulator plant species for soil remediation, and introduced the concept of phytomining (a technology that uses such plants to accumulate soil Ni into the plant shoots where they can be harvested and used as an alternative ore for Ni).Nearly three decades later, Morel (2013, 2015) …

Phytomining technology employs hyperaccumulator plants to take up metal in harvestable plant biomass. Harvesting, drying and incineration of the biomass generates a high-grade bio-ore.

Suggéré par pour dépolluer les sols, le procédé a été testé par puis pour extraire des métaux comme le zinc et le cadmium. La phytoextraction a aussi été envisagée dans le but de valoriser les métaux en métallurgie ; …

The idea of phytomining was first put forth in 1983 by an agronomist at the U.S. Department of Agriculture named Rufus L. Chaney.

Ultramafic soils are typically enriched in nickel (Ni), chromium (Cr), and cobalt (Co) and deficient in essential nutrients, making them unattractive for traditional agriculture. Implementing agromining systems in ultramafic agricultural soils represent an ecological option for the sustainable management and re-valorisation of these low …

April 7, 2020. An hour's drive south of San Francisco, a stand of several hundred poplars grows in a Y-shape — a rather unusual sight wedged between two baseball fields. The trees were planted ...

The Phytomining method is eco-friendly, which has resulted in a growth in mineral demand in recent years, thus promoting the development of a preferred phytomining process. View Show abstract

Phytomining extracts critical minerals used in EV batteries and elsewhere from a plant's biomass. The United States should incentivize R&D of innovative production techniques like phytomining to support U.S. critical mineral independence.

Phytomining is a plant-based mining technology in which accumulator or hyperaccumulator plants are used to accumulate soil metals into aerial parts of the plant e.g. shoots, where they are treated as "bio-ore" for the recovery of metals (Robinson et al., 1997; Anderson et al., 1999; Van der Ent et al., 2018a, Van der Ent et al., 2018b; Chen ...

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.

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 …

But what is phytomining?. Phytomining, also known as agromining, is a method of extracting metals from an unusual group of plants named hyperaccumulators.Hyperaccumulators are plant that have evolved to thrive in metal-rich soils that would kill the average plant, and they actually draw-in and accumulate …

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.
