采矿和矿物加工仍然是许多发展中经济体长期环境问题的根源。植物修复已被证明是修复受污染土地和限制环境破坏的可行策略，但由于社会和经济挑战，它尚未得到广泛实施。然而，通过鼓励以植物提取为重点的植物补救，有可能恢复受污染的土地，同时向当地社区提供经济支持。这可以通过销售植物提取的金属来实现，以资助大规模的植物修复，特别是在撒哈拉以南非洲。为此，本文提供了一个概念性的方法，植物修复为基础的矿物恢复，并探讨了社会和经济的挑战，大规模部署。探讨了该方法的可行性，并确定了未来植物修复实施工作的目标是推进研究和合作。
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.
