Unreasonable choice of solid content (SC) and cement-to-tailings ratio (c/t), including pipeline networking system, will lead to some pipeline problems, such as blockage, wear, and rupture. Hence, this study deals with the ...

Under the oxidative roasting process, pyrite, as a major mineral in sulfidic mine tailings, can transform to iron oxides. Generated iron oxides, if exhibiting enough magnetic properties, can be recovered via magnetic ...

Understanding the flow process of cemented tailings backfill (CTB) is important for successful pumping into underground stopes. This study examines the effects of solid content (SC), cement/tailings (c/t) ratio, and curing ...

The artificial concrete pillar (ACP) replacement technique is a safe and reliable method to safely mine orebody pillar in room and pillar mining. in contrast to traditional ore pillar, artificial pillar has recently received ...

A full understanding of the mechanical response of cemented tailings backfill (CTB) under various loading scenarios is beneficial for mining engineering applications. This study experimentally investigates the stress - - ...

Cemented paste backfill (CPB) is broadly used for underground backfilling, improving the mechanical performance through the modification of its composition and, therefore, its microstructure and characteristics. in order ...

Cemented paste backfill (CPB), an engineered mix consisting typically of tailings, cement and water, has become a regularly used structural material in most mines worldwide. the performance of the CPB structure is dependent ...

The strength properties of cemented tailings backfill (CTB: an engineered mix of processing tailings, hydraulic binder and mixing water) is strongly affected by its structural integrity. However, our understanding of the ...

This study investigates the time-dependent rheological behavior of cemented paste backfill (CPB) that contains alkali-activated slag (AAS) as a binder. Rheological measurements with the controlled shear strain method have ...
