This study seeks to provide comprehensive mapping of research on the circular economy within the mining sector from 2000 to 2024, highlighting essential topics, prevailing trends, and prospective future directions. Utilizing a mixed-method approach that combines bibliometric analysis, text mining, and content analysis, the research pursues several objectives: (i) capture the scientific foundation of circular economic research in mining by identifying key themes and trends over the past 24 years, (ii) offer a comprehensive overview of the existing literature on the topic, and (iii) propose future research directions. 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.

This study explores the hedge and safe-haven properties of gold and Bitcoin against several financial asset classes: (i) developed market equities, (ii) emerging market equities, (iii) bonds, (iv) commodities, (v) energy, and (vi) cryptocurrencies. By employing multifractal cross-correlation analysis, the paper investigates whether gold or Bitcoin qualify as hedgers under stable market conditions or as safe havens during extreme market movements. The analysis of individual assets reveals that the variables exhibit multifractality, statistical self-similarity, and market inefficiency. Furthermore, the hedge analysis of bivariate portfolios indicates that neither gold nor Bitcoin can be classified as a hedge or safe haven for financial markets. The only notable risk reduction advantage is observed in the gold-bond pair. This study provides valuable insights into hedge and safe-haven dynamics in financial markets through the lens of nonlinear dynamics, offering significant practical implications for policymakers and investors.

Dig-limit optimization is a crucial step in the grade-control process for open-pit mines. 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.

The need for sustainable utilization of mine wastes is increasing day by day. One of the uses that can meet this need is the use of mine wastes in agriculture and soil improvement. There is a lack of information in the literature about which mine wastes can be utilized for this purpose and what kind of sustainability contributions each of these wastes makes. In the literature, it is noteworthy that studies on the use of phosphate, potassium, coal and natural stone mine wastes as fertilizers in agriculture or in soil improvement have been carried out more intensively compared to other mine wastes, and the high capacity of these mine wastes to nourish the soil. Accordingly, in this study, the literature on the use of selected mining wastes in soil remediation and agriculture was reviewed. Firstly, the contributions to sustainability criteria of these mine wastes in agriculture and soil remediation were determined. Studies in the literature were reviewed, and the sustainability criteria to which these mine wastes contribute were also determined. Additionally, as a result of the studies conducted, it was also revealed which mine wastes contribute to each sustainability criterion. In this study, it was determined that the sustainable contributions of the selected mine wastes in agriculture & soil improvement were at a high level. According to the literature, applicable results can be obtained when these mine wastes are mixed with other wastes such as domestic or industrial wastes.

The notion of social license become crucial in the mining sector mainly in developing countries due to rising in resource-related disputes and local community's aspirations for more participation and benefits. The context of social license to operate, and implications on mining development were assessed in this study, focusing on Tulu Kapi Gold Mining in Western Ethiopia. The qualitative methods were embedded in the statistical analysis for data collected from 116 participants from household heads, elders, women, and experts. Regardless of the expected adverse of mining, the local community supports the projects' operation in their area. However, the firms have hardly considered social acceptance that the observed trust index for most of the SLO indicators were remarkably low. The issues have dimensions along social groups that elders, women, and landless households were more concerned but are less engaged and showed maximum aversion. These conditions have been deteriorating community-companies relationships, and reducing effectiveness of mining operations. The situations have significant implications for the sector and the local community's welfare; and seek policy and practical attention in Ethiopia.

The study examined the institutional arrangements for reducing the vulnerability of cocoa farmers in two mining districts of Ghana. Using a qualitative research design, state institutions mandated to oversee mining and cocoa production, as well as informal institutions, traditional institutions, and cocoa farmers’ associations, were selected for the study. Data were collected through key informant interviews and group discussions and thematically analysed. We found that the state institutions mandated to regulate mining in Ghana work independently with no direct policies to protect cocoa farmers from artisanal and small-scale mining activities, thereby making them vulnerable to livelihood shocks. In terms of land acquisition, the study found that the Minerals and Mining Act, 2006(Act 703) was not enforced as most miners preferred to deal with informal institutions for land acquisition with its resultant implications for adequate compensation to cocoa farmers. In addition, the institutions were oblivious to the Economic Plants Protection Act, 1979 (A.F.R.C.D. 47) 1, which was promulgated to protect plants of economic value, including cocoa. Though backed by laws and regulations, the state institutions were constrained by political interference and inadequate logistics, which hampered the effective monitoring and regulation of artisanal and small-scale mining activities. The study recommends an effective implementation of the relevant laws and policies to leverage cocoa farmers. Also, effective collaboration among state institutions devoid of political meddling is sine qua non to reducing the vulnerability of cocoa farmers.

Sustainable energy infrastructure is vital for addressing global climate challenges, and ESG investing has emerged as a key driver in greening private enterprises. This study examines the impact of ESG investing on private sector energy infrastructure investment in 20 OECD countries from 2010 to 2021 using an Autoregressive Distributed Lag (ARDL) model. Findings reveal that a 1% increase in ESG investment boosts short-term private investment by 0.15% and long-term investment by 0.26%. Conversely, economic risk and consumer price index reduce short-term investment by 0.43% and 0.27%, respectively, with similar long-term effects. Economic growth, human capital, and internet access enhance short-term investment by 0.31%, 0.29% and 0.54%. Long-term analysis shows a 1% increase in past investments leads to a 0.49% rise in future investments. To foster sustainable investment, OECD nations should enhance ESG regulations, standardize reporting, improve human resource management, promote green technology R&D, and raise awareness.

Many formalization of artisanal and small-scale mining (ASM) policies in Africa emphasize increasing tenure security through mining titles and the mandatory creation of cooperatives. These are promoted as a means of poverty-alleviation, reducing environmental harms, and ensuring community benefits, which could include the empowerment of women. Drawing from research conducted in gold ASM areas in Manica, Mozambique together with analyses of transnational law and policy on miners’ cooperatives and ASM formalization interventions, this paper examines how these efforts have expressed significant gendered and class inequities. It analyses how the authority and control rights of the associations/cooperatives privilege men who are local political or economic leaders, which in one case was widely celebrated as an early and leading example of the benefits of formalization. The result, we find, was reduced access to gold mining livelihoods for women. Our analysis underscores the importance of examining who actually receives control rights in formalization efforts and how these are gendered and classed in practice, rather than assuming the declared collective benefits such as gender empowerment will emerge from them.

Natural resources rents have decreased in the last decade, but the climate change and global warming emergency still requires urgent action to reduce further natural resources rent-seeking activities. This study contributes to the literature by analyzing how dependence on natural resources is determined by the risks and uncertainties of natural hazards. In particular, the influences of exposure and a lack of adaptation strategies on natural resources rents are estimated for a global sample of 119 countries from 2011 to 2019. The empirical results provide four interesting findings. First, increases in exposure have a decreasing effect on natural resources rents, while a lack of adaptation strategies has increasing effects. Second, the analyses for two subsamples show consistent findings for 85 developing countries, while both exposure and a lack of adaptation strategies reduce natural resources rents in 34 developed countries. Third, the analyses for five different natural resources rents (oil, coal, mineral, natural gas, and forest) are shown to be robust. Exposure to natural hazards reduces natural resources rents, except for oil rent, while a lack of adaptation strategies increases natural resources rents, except for coal rent. Last, the quantile regressions show that the effects of natural threats are more prominent in middle quantiles. The findings are checked using instrumental variable estimates and different robustness tests. The results highlight the importance of adaptation strategies to natural hazards to reduce natural resources rent-seeking activities.

The purpose of this study is to identify the factors that determine the dependence on minerals for 10 mineral-rich African countries in terms of managing sustainable mineral policy and to ascertain whether regulations and international cooperations have a moderating effect on the effects of factors that increase dependence level of these countries. With recently developed panel data approaches, the impacts of economic growth, mineral rent, trade openness, regulatory measures, and international collaborations on mineral dependency are examined for the period of 2000–2020. The results show that trade openness, economic development, and increases in mineral rent all lead to greater mineral dependency. On the other side, the expansion of international collaborations results in less dependency. Further, mineral dependency level is not directly impacted by strict regulations. In terms of moderating influences, it has been shown that international collaborations and regulations both counteract the trade openness's tendency to increase dependency, demonstrating the efficacy of these factors. Based on the findings, policies are recommended that international cooperation and partnership opportunities with other nations, global institutions and development organizations should be pursued aggressively.

Based on the findings, policies are recommended that international cooperation and partnership opportunities with other nations, global institutions and development organizations should be pursued aggressively.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"102 ","pages":"Article 105494"},"PeriodicalIF":10.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143177922","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}
