Eco-engineering soil from mine tailings for native plant rehabilitation (2016–2019)

Abstract:
Sustainable rehabilitation of tailings at metal mine sites is severely constrained by soil resource deficiency. Building on our recent findings of critical processes in soil formation from Cu/Pb-Zn tailings, we aim to develop an integrated technology through eco-engineering the mineralogy and organic constituents of tailings to initiate and accelerate soil formation by using magnetite tailings as a template. The technology will be underpinned by research to mediate and stimulate key biogeochemical and rhizosphere processes in the tailing-soil towards a functional 'technosol'. We aim to apply this technology at metal mines in Australia, to offset the soil required for rehabilitating tailings landforms with native plant communities.
