The minerals industry however could capitalise on this unique biological resource by adopting a new technology called phytomining Phytomining Phytomining is a method for literally farming metals by growing hyperaccumulator plants and then harvesting the biomass rich in a particular metal
It was proposed that the accumulation of nickel to toxic levels was a defense mechanism against insects feeding on the sap though Poaphilini moths have been observed to consume P balgooyi leaves the insects utilize the concentrated nickel for their own defensive mechanism against predators
Phytoremediation is a cost-effective plant-based approach of remediation that takes advantage of the ability of plants to concentrate elements and compounds from the environment and to metabolize various molecules in their tissues the cleaned soil can support other vegetation Mining of these extracted metals through phytomining is also

and defense against pathogens and herbivores 13 phytomining may either function as a standalone operation to retrieve the desired element or jointly with phytoremediation financing the costs
a commercial phytomining technology is discussed in more detail Nickel is ultimately accumulated in vacuoles of leaf epidermal cells which prevents metal toxicity and provides defense against some insect predators and plant diseases Constitutive up-regulation of trans-membrane element
Jan 18 2013· Phytomining is a new way of extraction of metals of low quality in heavily contaminated metallic conditions The extraction process is performed by plants the plants draw up the elements through their roots it is stored there as the plant grows and then the plant is burned to produce bio-ore

Phytomining or agromining is a technology that uses hyperaccumulator plants to take up heavy metals and recover them from the biomass for resource cycling
A new way is described to recover nickel from common rock-types by the use of nickel hyperaccumulator plants The idea of phytomining nickel was suggested earlier but never implemented This situation may soon change because the mining sector suffers from a poor image on account of the impact of mining on the environment and would like to reduce the pollution and high energy consumption
Ultramafic areas are critical for nickel Ni phytomining due to the high concentration of this element in their soils and the number of hyperaccumulators they harbor The aim of the present study was to evaluate the potential of the Morais massif an ultramafic area in Portugal for phytomining using the hyperaccumulator species Alyssum serpyllifolium subsp lusitanicum
