Research objective is to substantiate the relevance of mining transition to eco-friendly technologies of subsurface use. Methods of research include analyzing theory and practice of environmental technologies application and carrying out a multifactor experiment. Results. An efficiency criterion for mineral resources extraction technologies is proposed that involves reducing the effect made by the by-products of mining and processing enterprises on the state of the environment. The problem is considered of minimizing the environmental damage from storing silt coal in dumps and storages by utilizing their components. The mechanism of environmental pollution has been formulated. Aspects of metal recovery from beneficiation tailings in a disintegrator mill are investigated. A reduced threat to living matter is predicted by implementing the concept of radical waste-free processing of substandard mineral raw materials. The need to improve the processes of crushing, fine grinding, and classification of minerals in mills to reduce the waste of coal production, harmful to the environment, is noted. Conclusions and scope of the results. Deteriorated conditions of mineral deposits development raise the risk of man-made impact on the environment in coal-mining regions. The global human population grows resulting in increased resources production to respond to resource needs. The growing threat to living matter can be reduced by radical measures, the non-waste processing of substandard mineral raw materials being the priority. The research results can be helpful in the development of deposits of solid metal-containing technologically exposed ores

Abstract The article presents the history of collecting data on mineral raw materials export and import in Poland and balancing mineral raw materials resources. The methodology of gathering data was analyzed on the basis of the publication “The Balance of Mineral Resources Deposits in Poland”. This is the current title of the yearbook, the back issues of which are collected in the Polish Geological Institute-National Research Institute headquarters. During the last decades the institutions responsible for collecting and delivering data have changed and they were cited in the article along with the names of general editors of the publication and the authors of the chapter devoted to the exports and imports. As a result, data on mineral raw materials international trade have been presented every year. Moreover, the scope of data and the manner of their presentation were covered in the article. The information on Polish export and import of mineral raw materials has been compiled since the 1960s. Significant changes took place for more than 50 years not only within Polish but also in the world economy, and these economic conditions – the growing number of trade partners, changes in accounting for commodities or currency changes – were the main factors influencing the successive conversions of data presentations. The range of data grew significantly, the source of data altered several times and the methodology of data presentation changed a lot. Over time, there were data presented in longer hindsight and not only on exports and imports but also on the turnover balance. The balance is treated as a reflection of the domestic mineral raw materials sector and of a situation in world mineral economy. Thus, tendencies in the trade turnover have been presented for the last 30 years, for export, import and balance. Graphs were also included in the article showing such changes in relation to the value and magnitude of the trade turnover for all mineral resources and for particular groups – energy, metallic, chemical and rock raw materials. The most important raw materials – in terms of affecting the total balance in Poland – were also specified in the article.

A conclusion has been justified, that the institutional norms and rules existing for the mineral resources use relations, extremely poorly affect industrial and innovative aspect of the activity of the mineral and raw complex (MRC). Actually these norms and rules preserve a hypertrophied export and raw orientation of activity of the MRC enterprises. Perspective development of the domestic MRC has to be based on the considering of the requirements of a set of the institutional norms relating as directly to the sphere of production and reproduction of mineral raw materials, and to the industrial innovative regulation assuming transition to the economy of the highest technological ways. The purpose, tasks, the basic principles of the industrial policy in relation to MRC’s activity have been formulated. A methodical approach to the development of the strategic courses of the development of the geological sector has been offered. Suggestions for the improvement of the mechanisms of staffing of the sphere of mineral resources use have been given.

Aggregates and other mineral raw materials are important prerequisites for the continual development of the infrastructure and economic growth of a country. Th e production of these raw materials in Denmark amounted to c. 4.5 m3 per capita in 2012, which was 57% higher than the average in EU and EFTA countries (UEPG 2014). In this perspective, it is essential to locate and assess the Danish mineral resources in order to plan future exploitation, especially in densely populated regions where both spatial competition for landuse and demands for raw materials are high. Here we present the methods used in a recent resource evaluation that for the fi rst time includes Danish resources both on land and at sea and summarises some of the main fi ndings of this analysis.

The equivalent of 1 kg of cement using binders from processing tailings has been determined. The advantages of mechanochemical activation of tailings in a disintegrator in comparison with the option of irrigation by irrigation using various reagents have been experimentally determined. A quantitative indicator of an increase in the strength of the compositions of hardening mixtures under equal conditions has been established. The efficiency of utilization of tailings and metallurgy has been determined as a set of effects of reducing the amount of environmental damage from storage of tailings, the cost of metals obtained during processing, raw materials for the construction industry and associated marketable products. The nomenclature of tailings processing products has been detailed. A model for determining the profit from processing tailings and metallurgy is recommended. A forecast is given at the level of engineering expertise of the prospects for tailings processing. The hardware diagram of the tailings disposal section is detailed. A universal scheme for the disposal of mining and processing waste was recommended. Conclusion. The prospects for the development of the deposits of the Sadonsky ore cluster depend on conversion to technologies with filling voids with solidifying mixtures and leaching of metals at the processing stages. The combined mining technology will reduce the output of tailings, strengthen the base of the construction industry, eliminate the need to build a second stage of tailings and improve the environment.

Rational and long-term planning and sustainable mineral resources management is of strategic importance in Europe’s efforts to secure the self-supply of mineral raw materials. European mineral data is organized and accessible within the pan-European Minerals Intelligence Network. Most EU countries are part of this network, while the West Balkan region presents a gap in this regard. A common West Balkan mineral register needs to be established in order to close the gap and bring the area closer to the EU market. Including the region into the network would provide new opportunities to local industry and improve mineral management at the national and regional level. In this context, the Geological Survey of Slovenia is working in cooperation with numerous partners and stakeholders in different projects within the framework of European initiatives and programs. We collected and properly organized relevant data on minerals in the region according to the INSPIRE Directive. This paper describes the creation of the West Balkan Mineral Register of primary raw materials, and its content.

The mineral raw materials’ resource efficiency is currently recognized in Europe as the way for the future development of the European mining economies. With this aim, a West Balkan Mineral Register was created in the EIT Raw Materials RESEERVE Project, including Primary and Secondary Raw Materials of six Eastern and South-Eastern Europe (ESEE) countries, i.e., Albania, Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia, and Serbia. Within the Project, a Strengths, Weaknesses, Opportunities, and Threats (SWOT) and Gap Analysis was also performed for the development of the raw material sector in the region. This paper summarizes the main strengths to be exploited, i.e., the significant geological potential, the presence of critical raw materials (e.g., Sb, Co, REEs) in primary and secondary raw materials, and the challenges to address, i.e., compliance of resources/reserves classification with international standards, integration of state’s mineral policy with spatial planning strategies, improvement of the business environment, capacity building of the raw materials workforce and enhancement of the public acceptance of the sector, in order to achieve the sustainable development of the mineral resources of the six ESEE countries. These opportunities comply with the objectives of the EU Raw Materials Initiative and are expected to contribute in the further enhancement of those economies in transition for the upcoming years.

Abstract Growing awareness of limits set by exhaustibility of natural resources has led to a conclusion that only through their valuation in monetary terms one may assess a comprehensive economic impact of their use. Thus mineral resources have been included from the beginning to almost all studies regarding natural resources assessments. The first result, widely recognized by international community, of researches came in the 1993 – edition of the “Handbook of National Accounting: Integrated Environmental and Economic Accounting”. One of the key outcomes of these works was a conclusion that measuring value of mineral resources for mineral raw materials production, alongside with physical flows of these materials, environment related transactions and measuring impact of the economy on the environment, should make basic pillars of this newly designed system, later named as the System of Integrated Environmental and Economic Accounts (SEEA). As implementation of SEEA is still in a primary stage, many methodological issues remain unsolved. This article attempts to enumerate achievements made so far and indicate issues in need for further development. Taking into account the importance of mineral resources for further economic development of Poland authors indicate a necessity to develop and implement methodologies for monetary assessment of resources/reserves available, extracted and depleted in order to form a methodological base for a meaningful policy of sustainable growth. The special challenge results from monetary assessment of explored but yet undeveloped mineral deposits.
