Abstract

The exploration and utilization of mineral resources are essential for sustaining the economic development of modernsociety and human activities. However, over the past century, the extraction and processing of various mineral resources haveresulted in the generation of large amounts of mine tailings, posing significant threats to the local ecosystem and the sustainabledevelopment of human society. Ecological rehabilitation in mine tailing areas has become crucial for achieving sustainablemining practices. Building on an analysis of the shortcomings of traditional approaches to ecological restoration of tailings, wepropose a promising strategy rooted in pedogenesis principles for the sustainable rehabilitation of mine tailings. This strategy,termed“ecological engineering of soil formation in mine tailings”, treats tailings as the parent material for soil formation andemploys systematic ecological engineering methodologies to accelerate pedogenesis. The aim of ecological engineering is togradually transform the tailings into a stable soil-like substrates with a porous physical structure and chemical bufferingproperties, capable of supporting specific ecological functions, thus facilitating ecosystem development in the tailing areas.Throughout this process, it's essential to systematically consider the characteristics of the tailings, local microbial and plantspecies, and climatic conditions, in order to design technical routes tailored to local conditions and construct a comprehensivetechnical package. Finally, according to current research progress, we identify key research directions focusing on bothfundamental understanding and technical applications of ecological engineering of soil formation in tailings.
