Phytomining involves the production of a crop of metals by growing high biomass hyperaccumulators that accumulate high concentrations of metals Robinson et al 1999a In contrast to simple phytoextraction techniques the goal of phytomining is primarily to realize the economic benefits and commercialization by comprehensive use of

Phytomining ScienceDirect

There are practical limits to phytomining [13] The main variables that control its economic feasibility are the metal price the plant biomass and the highest achievable metal content of the plant Table 2 Metal values range from about $15 000 000 t − 1 for platinum to about $600 t − 1 for lead At these extremes a plant with a biomass of 20 t ha − 1 such as B

Phytomining In phytomining plants are grown on land containing the metal compound that we desire These plants absorb the metal compound and they concentrate it in their tissue The plants are then harvested and burned After being burned the ash contains a relatively high concentration of the metal compound

Biological Methods of Extracting Metals Revision MME

4 Phytomining is the process of using plants to extract copper from low grade ores in the ground Firstly areas of land must be found that contain a high concentration of low grade copper ores Once found plants are planted on this land and allowed to As the plants grow they absorb minerals from the ground in which they are growing This process causes copper
