Abstract Soils contaminated with multiple heavy metals pose a significant threat to human health and ecosystem functionality. Following “treat pollution waste” strategy, we synthesized Mg‐Fe‐Al ternary layered double hydroxides (LDHs) from waste Bayer red mud for the remediation of metal soils. Characterization using XRD, FTIR, SEM EDS methods revealed characteristic structure rich in functional groups, offering reaction sites passivation. Passivation experiments showed that application LDHs (2.5 wt.%) reduced availability Pb (29.7%), Cd (64.1%) Cu (66.0%) soil sulphide iron ore area southern Sichuan Province. Simulated acid rain leachate concentrations Pb, Cd, by 43.3%, 72.7% 42.4%, respectively. This work provides reference development high‐performance environmentally friendly adsorption‐stabilizing materials green remediation.
