In situ remediation in mine site rehabilitation

现场修复在矿山场地修复中的应用。通过加强和引导土壤发育的非生物和生物过程，该项目旨在加快铝土矿残渣(氧化铝精炼尾矿)的就地修复。全球每年产生超过70亿吨的尾矿，在极端的pH和盐度下包含复杂的矿物组合，生物活性最低。该项目将建立关于铝土矿残渣的化学、物理和生物特性的详细知识，并将其应用于制定现场规模的就地修复策略。这项研究还将促进对极端人为环境中土壤发育和微生物群落初级演替的理解，例如尾矿提供的环境。

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.
