Future research should examine the ecological risks associated with phytomining and phytoremediation (e.g. the secondary migration of contaminants due to improper handling of harvested plants). It is suggested that the results of field studies should guide commercial applications of phytomining and phytoremediation.

This concept of mining metals using plants is called phytomining. Plants that absorb metal compounds through their roots could be planted in contaminated soils, then harvested and the metals extracted for use in various industrial processes. Growing specific plants to remediate metal-contaminated soil isn't a new idea but extracting the ...

Advantages of phytomining. Phytomining offers the possibility of exploiting metals from low-grade ores, overburdens, mill tailings, or mineralized soil that is uneconomic by conventional mining methods (Nedelkoska and Doran, 2000). Its effect on the environment is minimal because of the stabilizing action of the plants when …

phytomining. 3 Recall advantages and disadvantages of phytomining. Introduction In today's technological society, there is an increasing need for valuable metals to use in computers and mobile phones. When the concentration of metal ore is too low for conventional mining, then phytomining, using plants, can be used to extract the metals.

Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, …

It has the advantage that it is very energy efficient typically using only 30% to 50 % of the traditional method. It has the disadvantage that it is very slow. Phytomining. Some plants absorb metal compounds (including copper) when they grow. The plants can then be burned and the metal is extracted from the ash. The process is called phytomining
