Phytomining is a recent phytotechnology based on the use of hyperaccumulators to recover economically relevant amounts of valuable metals from mineralized or contaminated soils [23,24].
Get PriceApr 13, 2015· field trials for phytomining, however, were carried out at the US Bureau of Mines in Nevada, the US, in 1994. A nickel hyperaccumulator was used in soil containing % of the metal, well below the economic range for conventional mining. The trial revealed that a yield of 100kg of nickel per hectare could be produced via phytomining.
Get PriceTest work on the absorption of gold by wheat has proved successful, when it is induced using a complexing agent. The plant species showed an absorption capacity of 90% and an attempt to increase this will be carried out. Different types of gold deposits will be tested to see the optimum mineralogy for gold phytomining.

Once phytomining is es tablished as a viable way of nickel production, it is likely that governments will impose nickel mines to realize part of their nickel production by this method. This will lead to a considerable decrease of CO. 2. emissions. Phytomining from rocks rich in olivine or serpentine is CO. 2nega tive.
