The biological synthesis of gold (AuNPs) and silver (AgNPs) nanoparticles using aqueous extracts of root, stem and leaf of Capsicum chinense was evaluated, obtaining the best results with the leaf extract. Gold and silver nanoparticles synthesized using leaf extract (AuNPs-leaf and AgNPs-leaf, respectively) were characterized by UV-visible ...
By changing of plant extract concentration, gold solution concentration, microwave heating time and power of microwave heating the optimized condition was identified. The surface Plasmon resonance found at 520 nm confirmed the gold nanoparticles synthesis. The spherical sized nanoparticles in the size range of 16-30 nm were confirmed by ...
Gold nanoparticles (GNPs) were prepared using four different plant extracts as reducing and stabilizing agents. The extracts were obtained from the following plants: Salvia officinalis, Lippia ...
The method of using plants to extract particles of gold from soil is called phytomining. It works by taking a fast-growing plant with leafy mass, such as mustard, sunflowers or tobacco, and planting the crop on soil that contains gold. Once the plants grow to their maximum height, the soil is then treated with a chemical to make the gold ...

4. Gives Plants Minerals From Soil. As I mentioned above, humic and fulvic acids help make nutrients available to plant roots. These acids are abundant in soil organic substances like leonardite, a sedimentation layer near the surface of the earth. When humic acid is present, important minerals and metals become absorbable through cell walls.
The presence of hydroxyl or amino groups in the plant extract play an important role in the process of reducing gold ions to metallic gold. This process can take place during an oxidation reaction or due to the formation of specific quinine forms [ 43, 60 ].
This method is quite simple to learn, and it is very cost-effective. You need a gold pan to extract gold from placer deposits, water, and patience! This approach will not produce as much gold as other techniques but is suitable for small-scale possibilities. Once you've found an outstanding placer deposit, shovel bits into your pan.
