  • Breakthrough technologies for mineral exploration

    • Free pre-print version: Loading...

      Abstract: Abstract Breakthrough technologies for mineral exploration are discussed from two perspectives. The first perspective is intended to discuss the important factors required for exploration technologies, derived deductively from a review of the role and expectations of exploration in the mining industry and the current situation of the mining industry. The second perspective is intended to discuss the common characteristics of breakthrough technologies for mineral exploration derived inductively from a review of specific examples of technological breakthroughs that actually brought about innovation to exploration: e.g. induced polarization (IP); airborne electromagnetics (EM); airborne gravity gradiometry (AGG); spectroscopic methods; global navigation satellite system (GNSS); unmanned survey platform; and neural networks/deep learning. The specific issues to be solved as breakthroughs in exploration technology in the near future are summarized as follows: Significant improvement in economic efficiency, namely: labor-saving, automated or unmanned operation, e.g. unmanned aerial vehicle (UAV)-based exploration and automatic spectroscopic scanning of drill cores; higher accessing capability, e.g. improvement of various airborne exploration techniques including airborne EM, AGG, and especially airborne IP; higher work efficiency and productivity, e.g. automatic data processing by neural networks/deep learning; and lower cost to implement, e.g. less expensive platforms such as UAVs. To obtain information that is really needed for exploration, specifically: IP effect of sulfide minerals associated with mineralization, i.e. practical spectral IP (SIP); geophysical characterization of the deep underground, e.g. enhancement of superconducting quantum interference device (SQUID)-based time-domain electromagnetic (TDEM); and removal of effects of the surface layer, e.g. very conductive deeply-weathered overburden and younger volcanics rich in magnetic minerals. To obtain information that could not be obtained by the conventional methods, specifically: distribution of endmember minerals related to mineralization, i.e. hyperspectral mapping with high spatial resolution.

  • Recycling and circular economy—towards a closed loop for metals in
           emerging clean technologies

    • Free pre-print version: Loading...

      Abstract: Abstract Resource efficiency, energy, and mobility transition are crucial strategies to mitigate climate change. The focus is on reducing the consumption of resources, especially energy and raw materials. While raw materials are the basis of our material world, their excessive consumption over the last decades has also contributed significantly to climate change. However, raw materials, and here especially metals, play a key enabling role as well for climate protection technologies, such as electro mobility, the hydrogen economy, and solar and wind power plants, and also for digitalization. Accordingly, it is necessary to make the use of raw materials much more resource-efficient than before and to use them as purposefully as possible instead of consuming them. Advanced circular economy systems and sophisticated recycling technologies build the backbone for the development of a resource efficient and sustainable society. Closed metal cycles contribute for a paramount share to this by securing relevant parts of the raw material supply for high-tech products and by reducing CO2 emissions in their production at the same time. Interacting steps in multistage treatment processes by mechanical, chemical, and thermal unit operations are challenging but will give a competitive advantage for networks of industry and science that are able to handle that.

  • Regional shifts in production and trade in the metal markets: a comparison
           of China, the EU, and the US

    • Free pre-print version: Loading...

      Abstract: Abstract Metal raw materials are essential for industrial production. Global metal markets have changed considerably since the start of the twenty-first century, China being the most influential driver of this change. With China’s economic rise, metal demand has skyrocketed, and global production shares in metal raw materials and trade volumes have shifted towards the People’s Republic. While China has become the dominant location for global metal production and consumption, older industrial economies like the European countries or the US have lost global share. This paper aims to compare the different developments in China, the European Union and the US regarding markets for the base metals aluminium, copper, lead, nickel, tin and zinc as well as iron and steel. The analysis covers movements in industrial production, metal production locations (mining – refined production – refined consumption) and metal trade volumes (ores and concentrates – waste and scrap – refined products and articles thereof).

  • The evolution of mining employment during the resource boom and bust cycle
           in Australia

    • Free pre-print version: Loading...

      Abstract: Abstract Mining employment in Australia can be cyclical and volatile. Since the gold rush in the 1850s, Australia has experienced two major mining booms. The first was in the 1970s and the second (i.e., the mineral boom) was in the mid-2000s and so it is important to have a discussion about trends in the Australian mining industry and about employment during mining cycles. This study employs Australian mining industry data to investigate sectoral labor mobility (moving from one industry to another) when the business cycles have changed. This research has used quarterly data from 1950q1 to 2018q4 for several industries such as mining, the building and construction industry, rental, hiring and real estate services, transport, postal and warehousing, agriculture, forestry and fishing, and manufacturing to conduct an empirical analysis. The findings of this study provide evidence that the sectoral shift of mining employment in Australia’s mineral and resource industry is highly correlated and dependent on the world economic circumstances. What happens in the world economies has an important bearing on how shocks are transmitted to the Australian mining industry and other sectors. The study also shows that displaced mining workers move around from one industry to another. In particular, the building and construction, agricultural, fishing and forestry, manufacturing, and real estate industries are found to be highly affected by the movement of labor.

  • How companies improve critical raw material circularity: 5 use cases

    • Free pre-print version: Loading...

      Abstract: Abstract This report showcases five examples of industries applying circular strategies for CRMs: (1) recycling of tungsten carbide scrap by H.C. Starck Tungsten, (2) recycling of battery cathode materials by SungEel Hitech, (3) recovery of rare earth elements from hard disk drives by Hitachi Group, (4) closed rhenium loops by Rolls-Royce, and (5) recovery of platinum group metals by Umicore. The adaptation of business models appears to be one of the biggest enablers of raw material circularity. Ideally, all involved stakeholders (including the manufacturers, the users, and the recyclers) have a common interest in, and are incentivized by retaining the material’s value, which stimulates transparent material flows and close cooperation. This is enabled by retained ownership and with long-term, well-defined relationships between the value chain actors. Such relationships can be enhanced by vertical integration, or by long-term contractual agreements. The benefits of implementing circularity provide a mandate for governmental intervention in stimulating circularity strategies, for example via regulations and subsidies, to overcome initial investment thresholds.

  • Coking coal futures price index forecasting with the neural network

    • Free pre-print version: Loading...

      Abstract: Abstract Coking coal price forecasting is a significant issue for investors and policy makers. This study explores usefulness of the nonlinear autoregressive neural network for this forecasting problem in a dataset of daily closing prices of the coking coal futures traded in China Dalian Commodity Exchange during January 4, 2016–December 31, 2020. Through examining various model settings across the algorithm, delay, hidden neuron, and data splitting ratio, the model leading to generally accurate and stable performance is reached. Particularly, the model’s inputs are the lagged coking coal futures prices and output is the 1-day ahead price forecast. The model is based on the two-layer feedforward network with six delays and two hidden neurons, which is trained through the Levenberg-Marquardt algorithm, and leads to relative root mean square errors of 1.84%, 1.85%, and 1.84% for the training, validation, and testing phases, respectively. Usefulness of the machine learning technique for the price forecasting problem of the coking coal price is illustrated. Results here might be used on a standalone basis as technical forecasts or combined with fundamental forecasts to form perspectives of price trends and perform policy analysis.

  • Mineral statistics—useful tool or needless exercise'

    • Free pre-print version: Loading...

      Abstract: Abstract Most of the international mineral statistics are limited to production, import and export figures only. However, such statistics are not sufficient to identify possible market trends or supply risks. The political restructuring in Europe and China’s rapidly increasing demand for mineral raw materials since the turn of the millennium has led to imbalances in the demand and supply of raw materials in many countries. In the present work, the importance of a more in-depth exploratory data analysis is explained. The paper also deals with the need to record raw material exploration projects. While most statistics are limited to the production figures and thus only allow a retrospect into the past only, information about the resources verified in exploration projects would also allow a glimpse into the future. Despite this need, many institutions that have compiled such statistics in the past have discontinued them meanwhile. Reduced budget and staff shortages are some of the reasons for this. For this reason, close cooperation between the few remaining organizations is urgently required.

  • Resources and reserves in a carbon-constrained world

    • Free pre-print version: Loading...

      Abstract: Abstract For many years, definition and production of non-renewable resources has been crucial to meeting industrial and societal demands for energy and materials. In the evolving energy transition, the priority is to meet not only the world’s increasing energy requirements but also societal expectations of net zero by 2050 or sooner. Renewable energy will play a key role in achieving this, but this will require key and critical minerals and materials, whether for use in wind turbines or for building new energy distribution systems. Fossil fuels will continue to be used for some energy and industrial processes and increasingly for the production of hydrogen. Essential to the energy transition will be ongoing assessment of resources and reserves, including of critical minerals, geological sites for CO2 and H2, carbon-based and carbon-free fuels. Some of the principles underpinning the traditional use of the terms reserves and resources can be usefully applied to provide rigour and uniformity to the assessment of renewable energy opportunities. Carbon offsets, negative emissions and recycling will also be used to achieve net zero. Whatever the energy transition pathway that countries choose to take, knowledge of and ready access to non-renewable resources and reserves will be essential to achieving a clean energy future.

  • Further investigation of the total natural resource rents and economic
           growth nexus in resource-abundant sub-Saharan African countries

    • Free pre-print version: Loading...

      Abstract: Abstract This paper analyses the effect of natural resource wealth on sustainable economic development in the top 8 resource-abundant sub-Saharan African countries according to the World Bank Wealth of Nations 2018 over the period 1981–2017. The study incorporates public debt as an explanatory variable in our analysis, which is an extension of previous natural resource-growth estimations, to throw more light on how natural resource abundance and debt overhang simultaneously affect economic growth in resource-abundant sub-Saharan African (SSA) countries. The NARDL bounds testing approach and asymmetric Granger causality tests are employed. Long-run asymmetric effect results show that an increase in natural resource rents significantly increases economic growth in Equatorial Guinea. However, an increase in natural resource rents in the Congo republic negatively affects economic growth, validating the resource curse hypothesis. No significant effect was found in other countries studied. In terms of asymmetric causality results, no bidirectional causality between natural resource rents and economic growth was noted. We, however, identified a weak unidirectional asymmetric causality relationship running from economic growth to resource rents in the Congo Republic and natural resource rents to economic growth in South Africa. The study, therefore, suggests the implementation of efficient public debt management policies and an improvement in the quality of institutions for effective management of public loans and resource revenues to stimulate economic development in these resource-rich countries.

  • Metallurgical infrastructure and technology criticality: the link between
           photovoltaics, sustainability, and the metals industry

    • Free pre-print version: Loading...

      Abstract: Abstract Various high-purity metals endow renewable energy technologies with specific functionalities. These become heavily intertwined in products, complicating end-of-life treatment. To counteract downcycling and resource depletion, maximising both quantities and qualities of materials recovered during production and recycling processes should be prioritised in the pursuit of sustainable circular economy. To do this well requires metallurgical infrastructure systems that maximise resource efficiency.To illustrate the concept, digital twins of two photovoltaic (PV) module technologies were created using process simulation. The models comprise integrated metallurgical systems that produce, among others, cadmium, tellurium, zinc, copper, and silicon, all of which are required for PV modules. System-wide resource efficiency, environmental impacts, and technoeconomic performance were assessed using exergy analysis, life cycle assessment, and cost models, respectively. High-detail simulation of complete life cycles allows for the system-wide effects of various production, recycling, and residue exchange scenarios to be evaluated to maximise overall sustainability and simplify the distribution of impacts in multiple-output production systems. This paper expands on previous studies and demonstrates the key importance of metallurgy in achieving Circular Economy, not only by means of reactors, but via systems and complete supply chains—not only the criticality of elements, but also the criticality of available metallurgical processing and other infrastructure in the supply chain should be addressed. The important role of energy grid compositions, and the resulting location-based variations in supply chain footprints, in maximising energy output per unit of embodied carbon footprint for complete systems is highlighted.

  • Market efficiency in non-renewable resource markets: evidence from
           stationarity tests with structural changes

    • Free pre-print version: Loading...

      Abstract: Abstract The dynamics of metal prices are highly significant for worldwide economic activity due to metals being key intermediate inputs to industrial production and construction and treated as investment assets. In that sense, this study investigates the efficient market hypothesis, i.e., predictability of price patterns, for several non-renewable resources, namely copper, lead, tin, nickel, zinc, aluminum, gold, platinum, and silver. Our period covers 1980Q1–2019Q4, during which metal markets witnessed many extraordinary times due to market-specific and global factors. Accounting for the importance of the potential breaks in the analysis of stochastic properties of non-renewable resource prices, we utilize two different stationarity tests; one is designed to capture smooth breaks, and the other one is designed to detect abrupt changes in the prices. Our empirical results reveal that none of the prices, except silver, can be characterized by the efficient market hypothesis. They follow stationary and predictable patterns with structural changes related to market-specific and global economic events, though concerns on economic uncertainties appeared to be more effective on precious metals.

  • Oil, export diversification and economic growth in Sudan: evidence from a
           VAR model

    • Free pre-print version: Loading...

      Abstract: Abstract There is an extensive literature demonstrating a positive link between export diversification and economic growth. In parallel, the resource curse thesis posits export concentration as an important mechanism curtailing growth in mineral-rich countries. Our analysis contributes to this literature by empirically investigating the interaction between oil dependence captured by the share of oil rents in GDP and export diversification and economic growth for Sudan. We do this with the help of a VAR model using annual data between 1960 and 2018. In comparison to earlier studies, our dataset covers also Sudan’s post-oil boom period, which coincided with a substantial drop in oil dependence after the 2011 secession of South Sudan. We find that oil rents appear to have a statistically significant and negative effect on export diversification, although contemporaneously rather than in the long-term. However, we find no evidence of a statistically significant impact of either oil dependence or export diversification on economic growth, as suggested by the resource curse hypothesis.

  • Current trends in addressing environmental and social risks in mining and
           mineral supply chains by regulatory and voluntary approaches

    • Free pre-print version: Loading...

      Abstract: Abstract Mining activities have always raised environmental and social concerns due to their impact on natural resources and people. During the last decade, the stakeholder base expected to respond to these sustainability concerns has broadened from directly involved parties to a range of indirect stakeholders along the downstream mineral value chain. These stakeholders variably engage in reporting, supplier risk assessments, exercising supply chain due diligence, third party assurance, and corporate social responsibility measures. This trend reflects a combination of societal, investor, and regulatory pressure as well as industry self-regulation along the supply chain. The present article examines this development from the complementary perspectives of international regulations and voluntary industry and multi-stakeholder initiatives affecting the industrial and the artisanal mining sector as well as the associated mineral supply chains. To this end, we provide an introductory analysis on the global uptake, implementation challenges, and lessons learnt with regard to both regulatory developments and voluntary initiatives. Key challenges identified include a misalignment between local reforms and international efforts, heterogeneous downstream market requirements, and evasive strategies as well as gaps to report on and achieve positive local sustainability impacts, partly brought about by emphasising corporate risk management over local community priorities. Meaningful stakeholder dialogue and increased local ownership are key factors to overcome some of these challenges.

  • What we have learned from the past and how we should look forward

    • Free pre-print version: Loading...

      Abstract: Abstract From the vantage point of more than 50 years’ work in the raw material field, as well as working in the private sector, in the German federal ministry of economics, at a geological survey, and engaged in teaching and supervising research at a university, I draw a number of conclusions about the following aspects of the fields: development of long-term prices, the long-term supply situation, especially the expectation of an imminent peaking of supply, the frequent and mistaken prediction of shortfalls in supply, our understanding of reserves and resources, and the cyclic nature of success in exploration. I am solely dealing with geological aspects, not taking into account political inferences and supply disruptions. This is followed by an attempt to look into the future of raw materials demand within the framework of the accelerating green energy transition. These conclusions are: Conclusion 1: When two amplifying effects overlap, long-term price trends can be broken. Conclusion 2: All growth rates flatten eventually. Never extrapolate high growth rates too far! However, growth rates are learning curves that move in waves and can steepen again. In general, the higher the production the lower the growth rates, even in exceptional cases. Conclusion 3: It is unclear, whether we have already reached the stage when growth rates of the major metals have flattened, but sooner or later it will come. Conclusion 4: Sooner or later we shall see demand peaking for primary metals of all commodities (in contrast to peak supply) because the share of secondary metals will grow and the consumption per capita reaches saturation levels. Conclusion 5: The reserve/ production ratio (R/P-ratio) is only a snapshot of a dynamically evolving reserve/resources system. The learning effects during exploration so far are in step with ever-increasing consumption. Serious limits to reserves are nowhere to be seen. Conclusion 6: Rapid changes in production rates may be accompanied by significant decreases in R/P-ratios and it would appear justified to suspect that advances in exploration cannot always keep pace with consumption. However, as long as the R/P-ratios do not fall below 50 for stratabound deposits and 25 for other deposits and exploration activities continue apace as normal there is no reason to worry about future supply bottlenecks. Conclusion 7: The R/P-ratios are useless as indicators for lifetime; however, they are helpful as early warning indicators for looming problems of supply and for indicating the need for boosting exploration. Conclusion 8: Exploration discoveries show episodic behaviour. Therefore it is difficult to extrapolate into the future. So far all pessimistic forecasts have been proven wrong by ingenious advances to detect new ore bodies to replace mined-out reserves. Conclusion 9: Supply shortages have been forecast frequently in the past. They never actually happened. The self-regulating feedback control cycle of mineral supply safeguards adequate supply over time. There is no reason to assume that this system of self-correcting forecasts will not work in the future.

  • Impact of metal mining on per capita family income in Peru

    • Free pre-print version: Loading...

      Abstract: Abstract The objective of the research was to measure the impact of metal mining production on per capita family income at the district level, during the period 2003 and 2019. For this purpose, the data from the United Nations report and the econometric methodology of difference in differences were used with and without spatial effects. The results without spatial effect show that the impact of mining on monthly per capita family income between 2003 and 2019 was 207.42 soles. However, considering the effects of spatial spillover, the total impact was 291.61 soles, which is decomposed into a direct and indirect impact of 189.77 soles and 101.84 soles, respectively. Likewise, the results suggest that there is a total impact of 77.25 soles on the per capita family income of the neighboring non-mining district. These results suggest that there is ample space for the design and implementation of public policies for the mining sector.

  • A method to estimate the robustness of the secondary refined copper supply
           function

    • Free pre-print version: Loading...

      Abstract: Abstract Knowing the factors that influence the secondary refined copper supply behavior has been fundamental in generating a copper market model and developing public and corporate policies. When analyzing the explanatory variables used in the existing models in the literature, it is possible to observe high variability in estimating the parameters when modifying the availability of information or changing the observation period. Based on this, we argue that only some explanatory variables will have robust estimated parameters, which means that they are unbiased, stable (i.e., they do not vary significantly when the specification of the equation or the number of observations changes), and with asymptotic convergence over time. This work defines and validates a method to select robust explanatory variables capable of quantifying the refined secondary supply of copper (or any other variable) in a given period. Using a database with 23 explanatory variables in the period 1960–2017, we characterize the estimated parameters with high and low robustness, thus supporting the proposed hypothesis. The results obtained allowed identifying those variables with low uncertainty in estimating their parameters, with a high statistical significance, and with a low standard deviation. This allows to obtain a robust function for the secondary refined copper supply in the long term, capturing essential elements of reality.
