In situ remediation in mine site rehabilitation

矿山现场修复中的原位修复。本项目旨在通过加强和引导土壤发育的非生物和生物过程，加速铝土矿渣（氧化铝精炼尾矿）的原位修复。全球每年生产超过70亿吨的尾矿，包括复杂的矿物组合，在极端的pH值和盐度下，生物活性最低。该项目将建立有关铝土矿渣的化学、物理和生物特性的详细知识，并将其应用于开发现场规模的原位修复策略。该研究还将促进对极端人为环境（如尾矿）中土壤发育和微生物群落初级演替的理解。

In situ remediation in mine site rehabilitation. By enhancing and guiding abiotic and biotic processes of soil development, this project aims to accelerate the in situ remediation of bauxite residue (alumina refining tailings). Over 7 gigatonnes of tailings are produced globally every year, comprising complex mineral assemblages at extremes of pH and salinity with minimal biological activity. This project will build detailed knowledge on the chemical, physical, and biological properties of bauxite residue and apply this to develop field-scale in situ remediation strategies. This research will also advance understanding of soil development and primary succession of microbial communities in extreme, anthropogenic environments such as those presented by tailings.
