Assessment of rheological and sedimentation characteristics of fresh cemented tailings backfill slurry 

Cao, Shuai; Xue, Gaili; Yilmaz, Erol; Yin, Zhenyu (Taylor & Francis Ltd, 2020)
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 ...

Influence of Hydrofluoric Acid Leaching and Roasting on Mineralogical Phase Transformation of Pyrite in Sulfidic Mine Tailings 

Koohestani, Babak; Darban, Ahmad Khodadadi; Mokhtari, Pozhhan; Darezereshki, Esmaeel; Yilmaz, Erol; Yilmaz, Elif (Mdpi, 2020)
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 ...

Influence of Solid Content, Cement/Tailings Ratio, and Curing Time on Rheology and Strength of Cemented Tailings Backfill 

Li, Jiajian; Yilmaz, Erol; Cao, Shuai (Mdpi, 2020)
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 ...

Strength development and microstructure characteristics of artificial concrete pillar considering fiber type and content effects 

Cao, Shuai; Zheng, Di; Yilmaz, Erol; Yin, ZhenYu; Xue, GaiLi; Yang, FuDou (Elsevier Sci Ltd, 2020)
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 combined experimental and numerical study on the triaxial and dynamic compression behavior of cemented tailings backfill 

Yang, Lei; Xu, Wenbin; Yilmaz, Erol; Wang, Qiang; Qiu, Jingping (Elsevier Sci Ltd, 2020)
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 - - ...

Characterization of early age behavior of cemented paste backfill through the magnitude and frequency spectrum of ultrasonic P-wave 

Yan, Baoxu; Zhu, Wancheng; Hou, Chen; Yilmaz, Erol; Saadat, Mahdi (Elsevier Sci Ltd, 2020)
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 ...

Effect of mineral admixtures on flow properties of fresh cemented paste backfill: Assessment of time dependency and thixotropy 

Jiang, Haiqiang; Fall, Mamadou; Yilmaz, Erol; Li, Yuanhui; Yang, Lei (Elsevier, 2020)
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 ...

Fiber length effect on strength properties of polypropylene fiber reinforced cemented tailings backfill specimens with different sizes 

Xue, Gaili; Yilmaz, Erol; Song, Weidong; Cao, Shuai (Elsevier Sci Ltd, 2020)
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 ...

Rheological Properties of Cemented Paste Backfill with Alkali-Activated Slag 

Kou, Yunpeng; Jiang, Haiqiang; Ren, Lei; Yilmaz, Erol; Li, Yuanhui (Mdpi, 2020)
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 ...
