Seasonal dynamics of nickel attenuation in acid mine seepage: implications for remediation strategies at BCL copper-nickel mine tailings, Botswana

Godirilwe, J; Otake, T; Kikuchi, R [Conference-Abstract]

Mining activities in Botswana have posed significant environmental challenges, notably acid mine drainage (AMD) resulting from sulfide ore processing at the BCL copper-nickel mine tailings. This generates AMD seepage ...
The Impact of gas impurities on CO2 storage in depleted oil field with carbonate reservoirs

Muer, A; Elakneswaran, Y [Conference-Abstract]

The carbon dioxide capture and storage (CCS) is considered as a promising technology for carbon dioxide emission reduction. High-purity CO2 mixture gas is separated from the flue gas and pumped into underground for a ...
An Investigation into the pretreatment methods for the extraction of platinum (Pt) from platinum oxide ores

Tatenda, MM; Park, I; Ito, M [Conference-Full-text]

Platinum (Pt) is known to be one of the rarest metals in the world.lt’s unique physical and catalytic properties make it largely valued across a number of various demand segments and technologies. The four main segments ...
Fundamental study of the influences of discontinuities on rock slope displacement due to excavation

Kubo, T; Zhang, C; Sainoki, A; Kodama, J [Conference-Full-text]

In the Higashikagoe limestone quarry, discontinuities are thought to be one of the factors contributing to the deformation of the rock slope. In this study, we investigated the impact of discontinuities and dip angles on ...
Silica and polyphenol-based adsorbents of heavy metals fabricated by enzymes

Maulidin, I; Nakashima, K; Naota, R; Takano, C; Kawasaki, S [Conference-Abstract]

Lead (Pb) contamination in water sources poses severe health risks to both humans and ecosystems. Conventional methods for Pb removal often rely on chemical treatments or expensive filtration systems, which can be ...
Experimental and numerical analysis of dynamic fracture processes in rock and rock-like materials using NRC vapor pressure agent

Min, G; Fukuda, D; Di, W.; Liu, H; Kawasaki, S; Cho, S [Conference-Full-text]

This study investigates the fracture characteristics of rocks and rock-like materials subjected to the Nonex Rock Cracker (NRC), a vapor pressure crushing agent. The NRC generates vapor pressure by instantaneously vaporizing ...
Prediction of overbreak phenomenon in tunnel blasting using ORF index

Sato, N; Im, H; Nakazawa, Y; Jang, H; Ohtomo, Y; Kawamura, Y [Conference-Full-text]

In the drill and blast method, one of the most critical issues is overbreak. Overbreak leads to decreased work efficiency and increased operational costs, and it is recognized as a problem that needs to be addressed. ...
Enhancing Co2 mineralisation in steel slag with amines for developing a waste to construction material

Takebe, K; Elakneswaran, Y; Yoda, Y; Kitagaki, R [Conference-Abstract]

Global warming has become an urgent issue due to the increasing atmospheric emission of CO2. In Japan, the steel industry emits a large amount of CO₂ and produces steel slag as an alkaline waste product. Using this steel ...
Development of a numerical simulation method for complex fracture process of rocks based on 3-D ECZM-FDEM using GPGPU parallel computation

Takarada, K; Fukuda, D; Di, W; Liu, H; Ogata, S; Maeda, Y; Min, G; Kawasaki, S [Conference-Abstract]

For the developments of surface and underground mines, numerical simulation has been regarded as a highly crucial approach in terms of mining design and safety. The combined finite-discrete element method (FDEM)[1] has ...
