 · This 2009 study concluded that that an Australian nickel phytomine could make about $11,500 in clear profit per hectare, per harvest if energy generation from the harvested biomass was also utilised. A …

 · This is a technology where plants are used to extract metals from waste rock, soil, or water. These metals can be recovered from the plant in its pure form, then be sold or recycled. Gold...

 · Phytomining of gold involves extracting gold from soil substrates by harvesting specially selected hyperaccumulating plants. Phytomining has potential to allow …

Phytomining remains an infant technology with plenty of room for improvement. Environmental concerns about gold phytomining, associated with the need for chelating agents to increase metal bioavailability, can be tackled by the use of less-persistent ligands.

 · Called phytomining, the technique of finding gold uses plants to extract particles of the precious metal from soil. Some plants have the natural ability to take up through their roots and...

 · For the past 14 years, the idea of gold phytomining to recover this gold resource has been researched by various scientific groups worldwide. A number of plant species have been tested under laboratory, greenhouse, and field conditions to determine their potential for use in the phytoextraction of gold.

 · phytomining is to recover a mineral (metallic) commodity for commercial gain. Consequently, phytomining almost always refers to the recovery of heavy metals. …

 · What is phytomining? Phytomining is the process by which metals are extracted from plants instead of mined out of the Earth. There are around 700 species of plants known as "hyperaccumulators" that overtime suck the soil dry of …

 · 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 soluble.

 · Mohan (2005) recommended phytomining to be a novel cost-effective technology to extract gold from larger residual dumps (mounds of tailings) and from low-grade ores at KGF (Kolar Gold Fields)...

 · What is it: Phytomining is a method of harvesting metal from the soil by growing plants with a lot of biomass in which to accumulate the ore. These are plants which can take up elements from the soil (at rates) orders of magnitude higher than normal plants. Alan Baker . These "hyperaccumulators" thrive on metals like gold, copper, and zinc.

Anderson Published 28 April 2014 Economics Indonesian Journal on Geoscience DOI: 10.17014/ijog.v1i1.171 New technology is needed to protect the safety and health of communities and the environment at ASGM locations in Indonesia.

 · Gold phytomining is primarily influenced by the concentration and chemical form of gold in mineralized soil and the suitability of the plants to the climatic conditions of the site...

 · 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 …

 · The precious metal gold can be found at high concentration in tailings dumps and waste rock piles at many mining locations around the world. Conventional …

Induced hyperaccumulation of gold by plants was first reported in 1998 by researchers from Massey University in New Zealand who proposed the idea of mining gold using plants (phytomining). Since that time research has been conducted to understand the conditions under which plants can be made to take up economic amounts of the metal. One key …

In this scenario gold phytomining is actually competing for resource with conventional technology. But at a gold price closer to US$1,000/ounce, conventional technology is not economically viable, leaving phytomining as a realistic option to generate profit from waste material.
