RESUMO
Mining and mineral processing continues to be a source of lasting environmental problems in many developing economies. Phytoremediation has proven to be a viable strategy to remediate contaminated lands and limit environmental damage, but it has not been widely implemented partially due to social and economic challenges. However, by encouraging phytoremediation with a focus on phytoextraction, it may be possible to rehabilitate contaminated lands while simultaneously providing economic support to local communities. This can be achieved by the sale of phytoextracted metals to fund large-scale phytoremediation, particularly in Sub-Saharan Africa. To this end, this paper provides a conceptual approach for phytoremediation-based mineral recovery and explores the social and economic challenges related to large-scale deployment. The viability of the approach is explored and future work on phytoremediation implementation is defined with the goal of advancing research and collaboration.
