  1. Re: Plants growing around gold deposits. GoldstalkerGPX Sun May 22, 2011 6:16 pm. All good advice above, grasses can give an indication, flax (not sure of spelling) grass may indicate a shallow depression in the ground that has filled with wash or top soil that is worth checking. Large trees ie ironbarks may also indicate deep ground and also.
  2. The possibility of turning base metals into gold has intrigued many scientists since the early alchemists, and the discovery of significant gold uptake by plants has long been a `philosopher's stone'. But background levels of gold in plants are usually very low, rarely exceeding 10 ng per g dry tissue (10 p.p.b.). Hyperaccumulator plants, however, have 100 times the elemental concentrations of.
  3. Of the native grass species Wallaby grass and Redgrass accumulated most of the gold; 21.64 mg/kg and 23.78 mg/kg, respectively. Blue mallee and Black wattle both accumulated significant amounts of gold 11.11 and 14.79 mg/kg in the stem tissue of the plants
  4. They say money doesn't grow on trees, but gold and other precious metals can accumulate in plants. Researchers recently discovered relatively high levels of gold in the leaves of a eucalyptus tree..

Gold (Au) often occurs in plants such as Phacelia sericea that grow near gold mines. These plants have been used by geologists to locate deposits of gold in soil The red dirt the Desert Trumpet grows in is likely near heavy metals like gold. The Trumpet is most commonly found in arid parts of the American Southwest. Big Sagebrush and Four Wing Saltbush have traditionally been used as indicator plants by gold prospectors in the US West The plant can accumulate 19.3 g Mn kg −1 dry weight when grown on Mn-rich soils . The efficiency of Alyssum serpyllifolium subsp. lusitanicum for use in phytoextraction of polymetal-contaminated soils has been examined . The plants have been grown on soils contaminated with Cr, Cu, Pb and Zn Plants sprayed with 2,4-D may accumulate lethal doses of nitrates. 'The troublesome weed' - hence an excellent source of bioenergy. The troublesome weed' - hence an excellent source of bioenergy. [21 Farmers are now growing maize and canola plants in the area, though, which soak up heavy metals quite nicely - gold as well as mercury. One scientists overseeing the project estimated farmers could get a kilogram of gold per hectare from doing this, which would help pay for the clean-up

  3. Recently, a team working at SSRL lead by Professor Jorge Gardea-Torresdey from the University of Texas at El Paso have shown that ordinary alfalfa plants can accumulate very small particles (nanoparticles) of metallic gold (1). The best-known materials that contain nanoparticles of metallic gold are gold colloids
  4. However, studies have demonstrated that gold can be accumulated, to varying degrees, by plant species including Brassica juncea, B. campestris, Trifolium repens, Sorghum helense, Raphanus sativus, Kalanchoe serrate and Helianthus annuus, with species-specific differences in the rates of gold uptake and distribution in planta
  5. 400-Year-Old Frozen Plants In Glacier Come Back To Life! Recently, researchers accidentally stumbled across a eucalyptus tree with exceptionally high concentrations of gold. When they further looked into the matter, they found that there was a sizable gold deposit around 100 feet beneath the plant
  6. But background levels of gold in plants are usually very low, rarely exceeding 10 ng per g dry tissue (10 p.p.b.) 1. Hyperaccumulator plants 2, however, have 100 times the elemental concentrations..
  7. A previous study has shown that gold ions accumulated by plants (Alfalfa) and stored in leaf and stem biomass can be reduced to form discrete nanoparticles of pure metal (Gardea-Torresdey et al. 2002). So one possibility is that gold ions absorbed by roots can be reduced in the plant tissues (Anand et al. 2016; Lintern et al. 2013)

gold can accumulate in plants. Furthermore, as confirmed at Pokukrom, tree bark sample results demonstrate biogeochemical absorption of goldby tree roots from the underlying gold mineralization beyond the complex regolith. So the gold in the tree bark may be an absorbed gold in solution translocated to. Fifteen years ago, Anderson first showed it was possible to get mustard plants to suck up gold from chemically treated soil containing gold particles. The technique includes finding a fast-growing plant with a lot of aboveground leafy mass, such as mustard, sunflowers or tobacco. The next step is to plant the crop on soil that contains gold Two common plants absorb and accumulate gold nanoparticles. Study author Xiaoen Luo and her fellow researchers used the field-emission variant of a transmission electron microscope (TEM) to analyze the plant samples. A TEM forms an entire image of an object almost instantaneously by sending a very thin beam of electrons through it Sampling is harder than it sounds, though. Different trees accumulate gold in different ways, so exactly the same species must be sampled across each site for valid comparisons When the plant transpires, pulling water up and out through tiny pores on its leaves, it will take up the gold water from the soil and accumulate it in its biomass. Then harvest. Getting the gold into plants is the easy part. Getting the gold out has proved more difficult, Anderson explained

The term hyperaccumulation was introduced to describe such plants. Of the many metals that can be hyperaccumulated, two of the more interesting are nickel and gold. Nickel is naturally hyperaccumulated by around 450 plant species, while plants can be forced to accumulate gold if the metal is made soluble in the soil (induced hyperaccumulation) There do seem to be a few plants that accumulate gold, perhaps because they are associated with microorganisms containing particular amino acids that complex gold. Given the fascination of people for gold it is not surprising that people experimented with gold for medical treatments. In the 8th century alchemists attempted to prepare elixirs.
