Large-scale mining is essential for global material supply and the energy transition but poses significant environmental challenges. Adopting CE strategies and practices can help mitigate these challenges by reducing waste, improving resource efficiency, and minimising environmental impacts. However, existing CE frameworks are focused on downstream value chain segments and lack crucial conceptual elements to guide CE adoption in upstream industries like mining. The study advances the literature on CE, responsible sourcing of minerals and sustainable raw material extraction by identifying three crucial conceptual elements missing from existing CE frameworks: (1) a clear communication of the <em>goal and boundary</em> of the industrial production system that the adoption of CE practices is targeting; (2) an identification of the <em>source and type of inputs</em> used by the system; and (3) a consideration of the <em>resource state</em> of these inputs and the subsequent structural wastes generated from them. These new conceptual elements allow for a system-level analysis of CE adoption tailored to the context of the mining industry.</div><div>Using the case of Chile, the study demonstrates how this new conceptual approach can be applied to map existing CE practices and strategies used in the mining sector. Findings reveal that Chilean copper and lithium mining companies are successfully adopting CE practices, such as using seawater in ore processing, remining and repurposing tailings, and remanufacturing mining machinery. This shows that there is significant potential for the mining industry to adopt CE thinking. However, the case study also highlights prevalent tendencies of a lack of systems thinking and additionality in the design of CE practices, which present significant challenges for the sector to adopt CE practices at scale.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"102 ","pages":"Article 105514"},"PeriodicalIF":10.2,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143463619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many developing countries exhibit relatively low levels of economic complexity, particularly in terms of their technological capabilities, which may pose a significant challenge to renewable energy projects. In this study, we investigate the effects of economic complexity and metallic minerals on renewable energy consumption. We investigate a panel dataset of 77 developing countries from 1995 to 2021 using multiple robust techniques, including feasible generalized least squares (FGLS), fully modified ordinary least squares (FMOLS), dynamic ordinary least squares (DOLS), canonical co-integrating regression (CCR), two-stage least squares (2SLS-IV) estimators and Dumitrescu–Hurlin causality analysis. The results indicate a negative relationship between mineral resources and renewable energy consumption. The results further suggest that economic complexity negatively affects clean energy production. Despite this, the robustness estimates confirm the positive moderating effect of economic complexity on mineral resources and renewable energy. These results have significant policy implications and underscore the need to explore the true potential of mineral resources in developing economies. This research calls for policymakers to focus on the economic complexity of their economies to escape the resource curse paradox and unlock the full potential of metallic minerals for transitioning to cleaner energy sources.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"102 ","pages":"Article 105512"},"PeriodicalIF":10.2,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 136 peer-reviewed articles from Scopus, JSTOR, and Taylor & Francis databases were analyzed, selected through the PRISMA method and ad-hoc sampling. The analysis identified three main research areas: (1) circular economy strategies for tailings and waste management in mining, (2) regulatory challenges and opportunities for circular economy implementation in mining, and (3) value chains within the circular economy in the mining sector. Based on these areas, four key lines of future research were proposed: innovation in tailings and waste management, regulatory and governance challenges, integration of technologies in sustainable value chains, and design of mine closure and rehabilitation strategies under circular economy principles. These recommendations aim to enhance sustainability and optimize resource use in the mining industry, promoting practices that contribute to a more responsible and efficient global development model.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"102 ","pages":"Article 105513"},"PeriodicalIF":10.2,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During short-term planning, blasthole data is used to generate an updated block model, typically, with a finer spatial resolution than the loading equipment's selectivity. Consequently, short-term planners must define operational dig-limits, determining the destination of each Selective Mining Unit (SMU) while accounting for the shovel bucket's size. This task is labor-intensive, highly time-consuming, and prone to SMU misclassification, potentially reducing profit and target fulfillment in the operation. To address these challenges, we propose a novel optimization model for defining optimal dig-limits for open pit mining. The model extends the state-of-the-art by including a wide range of destinations with capacity and blending constraints, and differential selectivity by equipment. Three case studies demonstrate the application of the model in short- and medium-term planning setups. Results indicate an average profit improvement of 7.3% compared to manually drawn dig-limits. Additionally, capacity and blending constraints significantly influence the optimal SMU assignment in scenarios with multiple destinations. The proposed model is computationally more efficient than existing exact methods, solving larger benches and complex setups to optimality using an off-the-shelf solver. This enhanced efficiency and versatility make the model a valuable tool for improving grade-control workflows in open-pit mining operations.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"102 ","pages":"Article 105510"},"PeriodicalIF":10.2,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143394514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, as a result of the studies conducted, it was also revealed which mine wastes contribute to each sustainability criterion.
