Simply put, PHYTOMINING is a form of EXTRACTION…. ADVANTAGES. DISADVANTAGES. The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women.
Advantages of Phytoremediation. The advantages of phytoremediation cannot be overemphasized. The cost of planting and maintenance is relatively low when compared to other cleanup options. The establishment of self - sustainable ecosystems and the improvement of aquatic and terrestrial habitats are some of the benefits (Dwyer, 1997).
Advantages: In principle, plants that engage in phytoremediation of toxic elements could be harvested, thus removing these elements from the polluted site. The plants can be easily monitored; The possibility of the recovery and re-use of valuable metals (by companies specializing in "phytomining")

Phytoremediation technologies use living plants to clean up soil, air, and water contaminated with hazardous contaminants. It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". The term is an amalgam of the Greek phyto (plant) and ...
