The best candidates for phytomining are gold, thallium, cobalt and nickel due to their high cost, high metal concentration in hyperaccumulator biomass (). Although metal prices of uranium are comparatively high, but its reported metal concentration (100 mg/kg) in biomass (10,000 kg/ha) is low, which makes it uneconomical for phytomining (plant …

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.
Phytomining's success is subject to the forces of nature. Unlike traditional excavation, phytomining is dependent on growing conditions such as the weather, altitude and soil quality. A bad growing season could wipe out an entire
Phytomining involves growing plants on top of low grade ores.The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions.These ions are leached from the ash using sulfuric acid.
