Analysis of Engineering Characteristics and Microscopic Mechanism of Red Mud-Bauxite Tailings Mud Foam Light Soil

Xiaoduo Ou et al.

Summary: In this study, a foam lightweight soil was developed using aluminum industrial waste-red mud and bauxite tailings mud. Experimental results showed that the synthetic sample with 16% red mud content exhibited the highest water stability and unconfined compressive strength. SEM images revealed that the addition of 16% red mud tightly wrapped the waste particles, increasing the structural compactness. Alkali leaching analysis showed that the sample with 16% red mud had the highest concentration. Based on mechanical strength and alkali release analysis, the sample B24R16 was selected as the optimum. This study provides a way to reuse aluminum industrial waste and has potential applications in roadbed and mining filling.

Numerical Simulation of Tailings Flow from Dam Failure over Complex Terrain

Yi Yang et al.

Summary: A tailings dam failure can have disastrous impacts on people's livelihood and the surrounding ecological environment. This paper studies the rheological properties and flow characteristics of tailings flow through rheological tests and Computational Fluid Dynamics (CFD) simulation. The analysis of a specific case indicates that downstream infrastructure will not be affected in a conservative scenario.
