There's Gold in Them Thar Plants Phytomining . 12-4-2013· Money doesn't grow on trees — but gold might. An international team of scientists has found a way to grow and harvest gold from crop plants. Called phytomining, the technique of finding gold uses .
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.
this species for phytomining was also evaluated and it was proposed that a yield of 100 kg=ha of Ni should be achievable at many sites worldwide with applied fertiliser and adequate moisture. 3. Phytomining for thallium 3.1. Introduction This subsection reviews phytomining for Tl and presents previously unpublished data on Tl in plants.

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.
Phytomining of gold: A review. 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 ...
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.

Jul 01, 2015· Gold was supplied in the culture medium by the addition of (AuCl 3, Sigma-Aldrich ®) 50, 150 or 300 mg L −1 at pH 4.0. The Petri dishes were incubated at 28 ± 2 °C for 11 days, and the fungal growth was assessed by measuring the diameter of each fungal colony every 24 h. Petri dishes without gold were used as controls.
Phytomining not only produces ingots of Gold but, interestingly and importantly, this technique can also be used to produce Gold nanoparticles, which is of huge potential to nanotechnology industries [211–213]. Additionally, phytomining provides a source of .
Most research to date has focussed on the phytoextraction of nickel because it has the highest number of known hyperaccumulators (some 300 species) and looks most likely to achieve commercialisation. Other likely targets for phyto-mining are the precious metals, gold, platinum and palladium and thallium.
Lastly, research on edaphic specialization, particularly the study of adaptation to edaphic factors such as nutrient levels, salt, heavy metals, and drought, will help counter growing challenges faced in fields such as agriculture (Rozema & Schat, 2013) and habitat restoration (O'Dell, 2014), and contribute to advancing green technologies, including phytoremediation and phytomining (Chaney et ...
This paper presents a review of reported gold phytomining trials developed in the laboratory, the greenhouse under soil and hydroponic conditions, as well as in the field, between 1998 and 2011.
