Mine Tailing as a Resource for Expansive Soil Stabilization: A Sustainable Perspective in Mining and Mineral Engineering

Journal of Mines Metals and Fuels, Journal Year: 2025, Volume and Issue: unknown, P. 243 - 257

Published: Feb. 24, 2025

This study investigates the stabilization of Black Cotton (BC) soil, an expansive and highly compressible soil type unsuitable for construction, through incorporation industrial waste materials. Rapid industrialization has escalated generation by-products, prompting need sustainable disposal solutions. research explores enhancement BC soil’s properties by reinforcing it with mine tailings (a by-product gold extraction process) lime. samples were stabilized at varying proportions, from 10% to 50%, additional 4% lime [Ca(OH)₂] in select combinations. The index engineering tailings, BC-mine tailings-lime mixtures assessed. Experimental evaluations conducted a prolonged curing periods 0, 7, 14, 30, 60, 90, 180, 365 days which is major gap identified literature survey. Scanning Electron Microscopy (SEM) analysis was performed on optimal combinations observe microstructural changes. experimental findings indicate significant improvement geotechnical addition lime, providing viable approach both tailing utilization. Major Findings: found that incorporating (10-50 %) significantly improved soil. Prolonged (up days) resulted enhanced strength reduced expansiveness, addressing key gap. SEM revealed changes contributed process.

Stabilisation of Black Cotton Soil Using Red Mud: An Alumina Extraction Byproduct

Journal of Mines Metals and Fuels, Journal Year: 2025, Volume and Issue: unknown, P. 969 - 979

Published: April 16, 2025

This study investigates the stability of Black Cotton (BC) soil which is known for its high shrinkage and compressibility difficulties in civil engineering by reinforcing it with Red Mud (RM), an industrial waste by-product from Bayer aluminium process, lime [Ca (OH) ]. To address issues weak BC disposal, sample was mixed RM increments ranging 10% to 50%, effect adding 4% also investigated. The index characteristics these stabilised combinations were tested during lengthy curing periods (0, 7, 14, 30, 60, 90, 180, 365 days), filling a large gap literature about long-term impacts on expansive soils. Scanning Electron Microscope (SEM) examination performed improved better understand microstructural alterations that contribute strength increases. findings show, addition 30% optimum greatly enhanced qualities over time combination 40.07 kN/m2 116.31 immediate testing. Following 365-day period, UCS rose 615.49 kN/m2, demonstrating effectiveness this stabilising method applications. As analysis, mixture BCS promotes gradual densification process time. stabilisation efficiently transform original loose, porous structure into consolidated matrix mechanical properties. Major Findings: demonstrated incorporating along significantly geotechnical properties soil. An extended period up days reduced expansiveness. SEM analysis highlighted transformations played major role process.
