Mineral Biosequestration of Organic Carbon in Early Pedogenesis of Tailings

将尾矿升级为土壤（由技术源母材开发的技术溶胶）为克服严重的表土短缺提供了一种可持续的方法，表土短缺限制了整个矿区尾矿生态恢复的进展。本项目旨在建立关于矿物生物风化、快速形成的矿物阶段有机碳（OC）封存以及在有机和无机物质输入的尾矿早期成土作用中由微生物和植物根系定殖驱动的有机碳转换的新知识。为了实现可持续的尾矿修复和有机碳封存，开发适用于多种矿物学尾矿的生态工程技术需要这些新知识。

Upcycling tailings into soil (technosols developed from technogenic parent materials) offers a sustainable approach to overcome severe topsoil shortage that limits the progress of ecological rehabilitation of tailings across mine sites. This project aims to establish new knowledge on mineral bioweathering, organic carbon (OC) sequestration in rapidly formed mineral phases, and OC turnover driven by colonising microbes and plant roots, in the early pedogenesis of tailings initiated by inputs of organic and inorganic materials. This new knowledge is required for developing eco-engineering technology adaptable to a wide range of tailings of diverse mineralogy, to achieve sustainable tailings rehabilitation and organic carbon sequestration.
