Abstract

ABSTRACT Phytostabilization on sulfidic mine tailings is not yet commonly implemented in the field, making it a crucial area of focus for future reclamation efforts. This greenhouse study aimed to explore cost-effective amendments on metal(loid) immobilisation and identify grass species candidates for phytostabilization. This research found that (1) wheatgrass (Pascopyrum) and ryegrass (Lolium multiflorum) are suitable candidates for phytostabilization, and (2) it is cost-effective to reuse wastes of bauxite residue and compost to promote phytostabilization effectiveness. Compost should be carefully evaluated for phytostabilizing Zn in tailings since the Accumulation Factor and Translocation Factor of all selected species are large than 1.

利用含硫尾矿成本效益高的改良剂鉴定植物稳定和增强金属（类）固定的候选草种

硫化尾矿的植物稳定化尚未在现场普遍实施，这使其成为未来复垦工作的一个重要关注领域。这项温室研究旨在探索具有成本效益的金属（类）固定化改良剂，并确定植物稳定的候选草种。本研究发现：（1）麦草（Pascopyrum）和黑麦草（Lolium multiflorum）是植物稳定的合适候选者；（2）利用铝土矿残渣和堆肥的废物来提高植物稳定效果是经济高效的。应仔细评估堆肥对尾矿中锌的植物稳定作用，因为所有选定物种的积累因子和迁移因子都大于1。
