Unfortunately, most publications focus only on one aspect of phytomining, such as phytomining for a particular metal (gold or nickel) [12] and metal hyperaccumulators [20]. Also, few e orts have been made to review phytomining-related studies systematically, and none of them have been reviewed in a visualizing way through scientometrics method.

This review critically evaluates influencing factors in phytomining and phytoremediation approaches, including contaminant concentrations, fertilizer application and chelating agent addition, planting characteristics (e.g. plant density, seeding, cropping and harvesting methods), and soil properties (e.g. salinity, soil texture and soil pH).

However, availability of resource for phytomining has been limited in recent years. As the gold price crept closer to US$2,000/ounce, companies began to review options for re-processing historic tailings using existing facilities. In this scenario gold phytomining is actually competing for resource with conventional technology.

Phytomining of gold: A review - ScienceDirect. May 01, 2013· Phytomining of gold involves extracting gold from soil substrates by harvesting specially selected hyperaccumulating plants. Phytomining has potential to allow economic exploitation of low grade ores or mineralized soils that are too poor for conventional mining of metals.

This study reports on the capability of the desert plant Chilopsis linearis (Cav.) Sweet (desert willow) to uptake gold (Au) from gold-enriched media at different plant-growth stages. Plants were exposed to 20, 40, 80, 160, and 320 mg Au L −1 in agar-based growing media for 13, 18, 23, and 35 d. The Au content and oxidation state of Au in the plants were determined using an inductively ...

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.

Phytomining of gold involves extracting gold from soil substrates by harvesting specially selected hyperaccumulating plants. Phytomining has potential to allow economic exploitation of low grade ores or mineralized soils that are too poor for conventional mining of metals. Gold is the most promising option for phytomining as its market value is increasing continuously.

In this review, bioremediation is defined as a process, which relies on biological mechanisms to reduce (degrade, detoxify, mineralize or transform) concentration of pollutants to an innocuous state. The process of pollutant removal depends primarily on the nature of the pollutant, which may include: agrochemicals, chlorinated compounds, dyes ...

Phytomining provides a further green method of managing the metal content of wastewater. These approaches represent a viable means of removing toxic chemicals from the effluent produced during the process of manufacturing, and the bioremediation process, furthermore, has the potential to save metal resources from depletion.

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.

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 metal is of sufficient economic value, smelted, and recovered.

In a recent review of the status of phytomining, Robinson et al. described how working models for the construction of infrastructure to process metal-rich biomass to yield saleable metal are lacking . Gold phytomining at ASGM locations will depend on simple technology to recover the final metal product.

The current state, problems, and prospects of phymoremediation of heavy metal polluted soils are analyzed. The main attention is paid to the phytoextraction and phytostabilization as the most widespread and alternative methods of soil phytoremediation. The efficiency of phymoremediation is related to the natural capability of plants for the accumulation and translocation of metals, their ...

Phytoremediation technologies use living plants to clean up soil, air, and water contaminated with hazardous contaminants. It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". The term is an amalgam of the Greek phyto (plant) and ...

Phytomining is climate and season dependent, limited by biogeochemical factors viz. rhizobiological activity, root exudates, temperature, moisture, pH and concentration of competing ions affecting the growth rate of plants, and the solubility and availability of the metals in the soil (Ghosh and Singh, 2005). Plant requires the metal to be in ...

Once applied at large scale, phytomining may either function as a standalone operation to retrieve the desired element or jointly with phytoremediation, financing the costs of the latter. This chapter reviews the advances of phytomining since its inception in the 1990s, focusing on the results obtained to date, with gold, nickel, thallium, and ...

2. Description of technology Phytomining consists in plantations that have the ability to accumulate high metal concentrations from mining waste areas, tailings or even from soils with low-grade ores (Brooks et al., 1998). This technology evolved from an area of research called phytoextraction in which phytoremediation is an application.
