The extraction and processing of iron ore produce significant amounts of mine tailings,
causing environmental problems that require storage in reservoirs or dams. Using these …

The high volume of mining tailings generated imposes difficulties regarding the final
disposal of these materials, commonly requiring large structures for containment …

Cement stabilized rammed earth construction using calcium-based materials (eg, Portland
cement), has been done for decades. However, consumption of Portland cement has …

Iron ore tailings (IOT) are generated in large-scale around the world and are stored in its
slurry form generating risks of dam failure. The stabilization of this tailings by cementing …

Stacking compacted filtered tailings has become an option to cope with the new Brazilian
regulations while providing a safe disposal method for the tailings. It has become feasible …

Cemented tailings find various applications in mining, such as open-pit and underground
backfill, dam decommissioning and filtered tailings stacking. This research investigates the …

The filtered tailings disposal (dry stacking) up to 300 m high is an alternative to overcome
the drawbacks related to the slurry tailings storage in large impoundments as it is safer and …

Brazil is one of the top world iron ore producers. However, it implies the generation of
millions of tons of iron ore tailings (IOTs). Dewatering technologies now permit the …

The technique of mass soil stabilization using alternative binders to Portland cement (PC)
has been used successfully in the past. However, knowledge gaps exist regarding the …

Catastrophic failures of tailings dams, primarily due to liquefaction, have occurred in Brazil in
the last few years. Mine tailings deposited behind upstream dams are materials of low in situ …
