Phytomining is generally considered a green technology as compared with the conventional mining practices. Phytominers can recollect metal pollutants from metal-contaminated soils, thereby restoring the soil to its original health and vigor. However, the economic feasibility of phytomining depends on the market price of the metal, the annual ...
