Phytomining
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 …
