A new reservoir model for the Donghae-1 gas field was constructed using existing seismic and well data for the Donghae gas field, through which carbon dioxide injection simulations were performed according to various injection scenarios. As a result of the simulation, it was found that the Donghae-1 gas field has a safe storage capacity of 400,000 tons of carbon dioxide injection per year for up to about 28 years; this is the initial target rate of the CCS demonstration project using the Donghae-1 gas field. These will be used as basic data for the project along with the results of additional research, such as the Geomechanics study.","PeriodicalId":17454,"journal":{"name":"Journal of the Korean Society of Mineral and Energy Resources Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135979029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This rapid increase in demand, coupled with geopolitical tensions, is impacting the raw material supply chains of strategic industries. In response, both the US and EU are formulating various legislative measures to ensure a stable supply chain and facilitate their domestic markets. The supply chain for these critical minerals requires close cooperation between various sectors such as industry, diplomacy, and trade, highlighting the need for an effective governance system for successful policy implementation. This study outlines the legislative timelines in the US and EU and examines their governance structures, specifically for the critical mineral supply chain. The comparative analysis presents the current status and challenges of governance, as well as strategies for a robust governance system in South Korea.","PeriodicalId":17454,"journal":{"name":"Journal of the Korean Society of Mineral and Energy Resources Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From site selection to operational stages, potential pathways for radioactive nuclide leakage into the ecosystem need to be completely delineated considering factors such as fractures and groundwater flow within the bedrock. For this purpose, geophysical survey techniques, which are non-invasive methods, have been actively researched worldwide. Utilization of various geophysical methods can evaluate geological and hydrogeological settings, thermal effects, engineering barriers etc. Analysis on previous geophysical survey cases conducted for URLs as well as repositories showed that geophysical surveys are sufficiently helpful and effective in assessing and managing deep geological repositories. The analysis can be used as fundamental information for the implementation of domestic disposal facilities.","PeriodicalId":17454,"journal":{"name":"Journal of the Korean Society of Mineral and Energy Resources Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135979027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight different DESs were prepared for leaching tests. The basic tests were conducted on Nd and Fe compounds, Nd2O3, Fe, and Fe2O3. Using GUC-LAC, ChCl-LAC, and EG-MA, Nd2O3 was leached by 64–100%. With the three DESs, Fe exhibited a leaching efficiency of over 94% in all DESs, while that of Fe2O3 remained low at <7%. Based on the results, leaching tests were conducted on NdFeB magnets with and without oxidative roasting. The leaching efficiencies of Nd and Fe significantly decreased after the roasting, at 27% and 4.7%, respectively. This was attributed to the formation of NdFeO3 during the roasting. Therefore, to selectively recover Nd from NdFeB magnets, the application of the appropriate pre-treatment method is necessary, prioritizing the separation of individual oxides to Nd2O3 and Fe2O3.","PeriodicalId":17454,"journal":{"name":"Journal of the Korean Society of Mineral and Energy Resources Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 3D reflection survey was conducted to determine the distribution and small-scale faulting of the Opalinus clay formation. Sweden conducted reflection surveys at the Forsmark site to obtain geological information on the deformation lenses within the site and to characterize the geology of the three deformation zones near the site.

Among these, the hard rock-type, particularly the LCT (Lithium-Cesium-Tantalum) pegmatites, stands out for its exceptional cost-effectiveness and developmental efficiency. LCT pegmatites originated from S-type granites; they exhibit compositional characteristics consistent with fertile granite and are enriched in Li, Cs, Be, Sn, Ta>Nb, B, P, and F. Leveraging these geochemical attributes, LCT pegmatites can be effectively explored by considering distinct factors such as the distribution of source rocks, geotectonic environment, and age dating. Current research deals with LCT pegmatites located in Uljin, South Korea, employing appropriate exploration methods including geophysical exploration and structural and geochemical analysis. The future objective involves constructing a 3D subsurface orebody model through the spatial integration of data derived from various exploration methods.","PeriodicalId":17454,"journal":{"name":"Journal of the Korean Society of Mineral and Energy Resources Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The commercialized process that relies on natural evaporation and concentration, typically applied to high-grade brine, has limitations when applied to low-grade brine. As an alternative, direct lithium extraction (DLE) technology is being proposed. DLE technology employs non-evaporative lithium extraction methods, including precipitation, solvent extraction, and adsorption, to recover lithium from low-grade brines (with lithium concentrations less than 1000 ppm). This technology is gaining importance, because it can overcome the drawbacks of conventional methods, such as lengthy processing time and production limits. This paper discusses the development direction of DLE technology that can ensure environmental and economic feasibility, using an analysis of the current status and trends of lithium recovery technology.","PeriodicalId":17454,"journal":{"name":"Journal of the Korean Society of Mineral and Energy Resources Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The boundary between the saprolite and bedrock was estimated using the change in the average penetration rate, calculated from the slope of the trend line of the drilling distance over time. The boundary between limonite and saprolite was estimated using “pressure-lift” and “pressure-rotate” data from MWD data, where the sign of the correlation value varied by lithofacies. By comparing the results of the lithofacies boundary estimation using MWD data with those of laboratory X-ray fluorescence analysis, the applicability of the reported method for estimating the lithofacies boundary using MWD data acquired during field exploration was validated.","PeriodicalId":17454,"journal":{"name":"Journal of the Korean Society of Mineral and Energy Resources Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
