Mineral raw materials prices have been shown to be affected by macroeconomic factors such as aggregate demand and commodity-specific factors (e.g., supply shocks). In addition, it has been shown that certain mineral raw material prices co-move, meaning that they behave similarly during expansion and contraction phases of the international business cycles. In order to assess the behavior similarity of the prices of different mineral raw materials, we propose a method that utilizes extracted features of time series price data and unsupervised learning techniques to create clusters of price movements having similar long-term behavior.

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.

Abstract Supply chains in the mineral raw material industry take different forms depending on requirements, the placement of resources and points of consumption, and the nature of geological, morphological and botanical landscape type. Hitherto, in the context of montanistic tourism, the attention is paid primarily to the objects associated with the exploration and exploitation of mineral resources. Professionally and touristically, processes of transport of mineral raw materials and products of their processing can be interesting. Therefore, during the selection, development and implementation of montanistic tourism products, it will be useful to focus on these parts of a supply chain, especially if they are implemented in areas with high levels of geodiversity and biodiversity.

The features of the geological structure and composition of the complex mineral raw materials of the combustible shale basins of the Russian Federation, Uzbekistan and Kazakhstan are considered. It is shown that oil shale, different in time of formation and composition, is a complex mineral raw material for the energy and chemical industries. The solution of urgent problems of forecasting, assessment and effective development of complex mineral raw materials requires a combination of the capabilities of basin analysis, mineralogical and technological research, modeling with elements of system engineering.

The article deals with the problems of mineral raw material losses of quality and quantity management in developing of large-scale complex-structure and composition deposits of solid minerals. It is shown that a very high degree of mining and geological conditions variability in time and space for the development of mining units is typical for such deposits. This significantly complicates the qualitative and quantitative operating losses setting and accounting of mineral raw materials during its extraction in the framework of existing general and industry regulatory documents. Conceptual principles for face-by-face operational setting of losses and impoverishment of minerals for the conditions of bulk mining of complex-structure deposits with the formation of gross mining flow with economically feasible and specified level of quality (the content of commercial and harmful components) are stated. These principles generally do not contradict effective instructions main provisions and are made to minimize the total operating losses during the processing of several mine sections (faces).

While the deposit qualities for mineral raw materials are constantly decreasing, the challenges for sustainable raw material processing are increasing. This applies not only to the demand for minimizing the consumption of energy, water, and reagents, but also to the reduction of residual materials, especially fine and difficult-to-landfill materials. Sensor‐based ore sorting can be used as a separation process for coarser grain sizes before the application of fine comminution and separation technologies and is applicable for a large variety of mineral raw materials. Sensor‐based ore sorting applies at various points in the process flow diagram and is suitable for waste elimination, for material diversion into different process lines, for the production of pre‐ and final concentrates, as well as for the reprocessing of coarse‐grained waste dumps and other applications. The article gives an overview of the development and state of the art of sensor‐based ore sorting for mineral raw materials and introduces various applications.

In the production of mineral raw materials in cupolas, as a by-product and harmful product, a significant amount of cast iron (up to 3 % of the raw material) is formed and, as a rule, thrown into the dumps. The article presents technical solutions that ensure the separation of mineral melt and cast iron. In addition, the article describes the results of optimizing the design of ladders used for draining liquid metal from the mineral wool cupola and transporting it. The resulting cast iron ingots can then be used as a charge in the smelting of branded cast alloys.

The subject of this research is the copper deposits, copper-ore resource, and sources of alloying raw materials for mining and smelting production of the Paleometal Epoch in Central Kazakhstan, namely within the Kazakhstan mining and smelting region and Zhezkazgan-Ulytau mining and smelting center. The article provides the interim results of comprehensive research of geoarchaeological production facilities in the territory of copper deposits within the Zhezkazgan-Ulytau mining and smelting center, which allow determining the peculiarities of metallogenic complexes that used to be potential objects of the development of copper-ore reserves during the establishment of copper metallurgy, as well as making a predictive assessment of mineral raw materials potential of the region. The initial premise of this research lies in the authors' pursuit to integrate natural scientific methods of research into the field of humanities to the maximum effect via studying smelting slags and ore relics from the ancient settlements of the region for the purpose of reconstructing the mining and smelting process of the Bronze Age in Central Kazakhstan. The authors offer the variants of localization of the mineral raw materials complex of Zhezkazgan-Ulytau mining and smelting center within the Kazakhstan mining and smelting region. Based on examination of the ores and smelting slags of Bronze Age settlements in Central Kazakhstan, the authors believe that the main copper raw materials in the Zhezkazgan-Ulytau region were the oxidized malachite-azurite and rich sulfide ores, as well as the zones of secondary sulfide enrichment of copper sandstones of the Zhezkazgan ore region. The conducted research allow to get closer to establishing patterns of localization of various types of copper deposits and development of copper-ore resources for mining and smelting production of Zhezkazgan-Ulytau region during the Paleometal Epoch.

This paper investigates an alternative use of sterile aggregate materials which may arise from various construction applications in conjunction with other low-cost mineral raw materials to remediate the acid mine drainage phenomenon. This study is based on the combination of unprocessed mineral raw materials, as well as on the basic concept of the cyclic economy where the conversion of a waste into a raw material for another application can be achieved. In this study, in order to examine the remediation, in lab scale, of the drainage waste water of Agios Philippos mine, an experimental electrically continuous flow-driven forced device was constructed, enriching the research gap relative to this type of remediation approach. Through this experimental device, the use of certain mixes of mineral raw materials (serpentinite, andesite, magnesite, peat, and biochar) was studied. Our results focus on the impact of the studied mineral raw materials and especially on their synergy on the water purification potential under continuous water flow operation. Using the new 7-day experimental electrically continuous flow-driven forced device with certain mixes of mineral raw materials, the increase of pH values from 3.00 to 6.82 was achieved. Moreover, with use of the experimental device, the removal of toxic load was achieved, and more specifically the concentration of Fe was decreased from 6149 to 1300 ppb, Cu from 8847 to 35 ppb, and Zn from 285,458 to 50,000 ppb.

The paper shows fundamental possibility of processing of gold-bearing technogenic raw materials using the method of electric explosion. A series of experiments using a laboratory and pilot-production high-voltage pulsed discharge (HVPD) installation for the processes of enrichment of gold-bearing mineral raw materials of Komsomolsk mine tailings in Kemerovo region is conducted with a relatively low energy electrical discharge in the pulse of up to 112.5 Joules and the cost of electric power of about 1.5 kW/ton of raw material, that allows complete destruction of clay components agglomerations to less than 0.045 mm (micron and submicron sizes). Solid minerals such as quartz are simultaneously destroyed by defects in the grains and withdrawn from the installation with water, thus increasing gold degree of the concentrate. The results of particle-size and X-ray structural analyses of gold-bearing mineral raw materials of Komsomolsk mine tailings in Kemerovo region obtained by the method of electric explosion are discussed.
