This study examines the compaction behavior of iron ore tailings, focusing on the influence of critical parameters such as water content, layer thickness, the number of compactor passes, and vibration technique. The results show that water content is the most crucial factor in preventing under-compaction, while the combination of optimal layer thickness and passes can significantly reduce compaction time without compromising quality. Furthermore, vibration improves compaction efficiency by reducing the required passes and increasing energy penetration depth. These findings provide practical guidance for enhancing the compaction process in tailings disposal, contributing to safer and more stable tailings storage facilities.en2590-12302026Elsevierhttps://creativecommons.org/licenses/by/4.0/DensificationField experimentIron oxideTechnology::620: EngineeringJournal Articlehttps://doi.org/10.15480/882.1720610.1016/j.rineng.2026.11100710.15480/882.17206
