Abstract:
Conventional mining, to extract metals economically, requires high grade ore and enormous investment. It also generates huge quantity of over burden / tailings. These tailings may contain other metals that could not be economically recovered by the mineral processing plants due to low concentrations. However, techniques making use of appropriate plant species comes handy in extracting metals in low concentrations distributed in low grade ore or mill tailings. Phytoremediation is another cost-effective, environmental friendly technology that can be employed for treatment of metal contaminated sites. It is reportedly feasible for exploiting the ores uneconomical to mine through conventional methods. For success of these technologies, continuous development and better understanding of the processes are imperative. In this context, we examine the present status of technology deployment, phytotechnologies for the extraction of metals by phytoremediation and implications for future research in this area.
