Mine tailings are the discarded materials resulting from mining processes after minerals have been extracted. They consist of leftover mineral fragments, excavated land masses, and disrupted ecosystems. The uncontrolled handling or discharge of tailings from abandoned mine lands (AMLs) poses a threat to the surrounding environment. Numerous untreated mine tailings have been abandoned globally, necessitating immediate reclamation and restoration efforts. The limited feasibility of conventional reclamation methods, such as cost and acceptability, presents challenges in reclaiming tailings around AMLs. This study focuses on phytorestoration as a sustainable method for treating mine tailings. Phytorestoration utilizes existing native plants on the mine sites while applying advanced principles of environmental biotechnology. These approaches can remediate toxic elements and simultaneously improve soil quality. The current study provides a global overview of phytorestoration methods, emphasizing the specifics of mine tailings and the research on native plant species to enhance restoration ecosystem services.
矿山尾矿是采矿过程中提取完矿物后产生的废弃材料。它们由残留的矿物碎片、挖掘的土地和被破坏的生态系统组成。废弃矿山土地(AML)中未经控制的尾矿处理或排放对周围环境构成威胁。全球范围内有大量未经处理的矿山尾矿被遗弃,需要立即进行复垦和修复工作。传统复垦方法的可行性有限,如成本和可接受性,这给 AML 周围的尾矿治理带来了挑战。本研究专注于植物修复作为处理矿山尾矿的可持续方法。植物修复利用矿山场地现有的本地植物,同时应用环境生物技术的先进原则。这些方法可以修复有毒元素,同时改善土壤质量。本研究提供了矿山尾矿植物修复方法的全球概述,强调了矿山尾矿的具体情况以及对本地植物物种的研究,以增强恢复生态系统服务功能。
