The mining industry in the world has undergone a major metamorphosis in recent years. These changes have forced higher education to modify the curricula in a thorough way to meet the mining entrepreneurs’ needs. The paper’s scope is to answer the research question—how to attract students and implement Sustainable Development Goals (SDGs) in higher education in mining engineering? Based on the case of international cooperation carried out at the Faculty of Geoengineering, Mining and Geology of the Wrocław University of Science and Technology (WUST) within the framework of educational projects co-financed by European Institute of Innovation and Technology (EIT) and EIT Knowledge and Innovation Communities Raw Materials (EIT RM), the authors prove that the idea of sustainable development can be introduced into the system of teaching mining specialists at every level of their higher education (engineering and master’s studies), through developing their new competencies, introducing new subjects taking into account innovative solutions and technologies, or placing great emphasis on environmental and social aspects. Examples of new curricula show a good way to change into the new face of a mining engineer.

Zinc scrap is a source of raw material for zinc oxide production. However, to qualify the requirement of raw material for zinc oxide (99.5%) production, refining this source is needed. Many methods are considered such as rectification, chemical method, etc., but difficult to apply on an industrial scale. This workfocused on the investigation of the influence of temperature and time factors for asessing the possibility of applying liquation method for the purification of impurities from scrap zinc.The experiment results show that the optimum temperature of liquation to remove Pb,Fe from zinc scrap is in the range of 440-450°C, the optimal time of the process is 8h for the pot with 8cm in height and 6cm in diameter (the quantity of raw zinc sample is about 2kg / batch), then we can obtain about 80% of zinc metal with an average Zn content of about 97, 0%, both Pb and Fe content decreased to a range from 0.35 to 0.4%, and 1.0 to 1.1%, respectively, which meet the requirement of raw materials for the production of high quanlity ZnO ( 99,5 %). Based on the parameters obtained on lab-scale, a trial on pilot scale of 250 kg / batch was conducted, The result confirms that the quality of the products meets the requirement of raw materials for production of high quality ZnO (99.5%) and a technology process for refining zinc scrap by the liquation was proposed.

The Government

The Import Facility for Export Purpose (KITE) is the Government's effort to encourage export performance. Companies that receive the KITE facility obtain fiscal incentives and export their product to import raw materials. The textile and textile product (TPT) industry is a strategic industry and has been determined by the Government as a pilot industry in the Roadmap for Making Indonesia 4.0. The textile industry relies on imported raw materials, so that the KITE facility is needed to encourage growth and increase product competitiveness in the international market. This study aims to determine the effect of the KITE facility, the rupiah exchange rate against the U.S. dollar, and the inflation rate on Indonesia's textile exports. We used a sample of 37 industrial textile companies in Indonesia that received the KITE facility  2016 to 2018. This study uses a panel data regression model with independent variables: KITE facility, exchange rates, inflation, and exported dependent variable. The results showed that the KITE facility had a positive and significant effect on the textile industry exports. In contrast, the exchange rate and inflation had a negative and significant impact on Indonesia's textile industry exports. This study's implications for the Government can be used to formulate a national strategy to increase export.

The Murmansk region is a region with the largest enterprises of the mining complex of the Russian Federation: KF JSC “Apatit”, JSC “Kola MMC”, JSC “Olkon”, JSC” Kovdorsky GOK”, JSC” North-West Phosphorus Company”, LLC”Lovozersky GOK”. They provide the majority of the country’s demand for phosphate ores, zirconium raw materials (baddeleyite), niobium, tantalum, and rare earth metals. In addition, the mining and processing of copper-nickel, iron and chrome ores, nepheline and ceramic raw materials, facing stone and building materials is carried out. At the same time, the activities of enterprises have a very negative impact on the environment. The issues of environmental safety in the extraction and processing of minerals, storage of mining waste in the Arctic zone of the Russian Federation are of particular relevance. The definition of sustainable development in relation to the mining industry is given. The concepts of available best technologies, circular economy, and “green growth” are considered from the point of view of their contribution to sustainable development. It is shown that the sustainable development of enterprises at the present stage is impossible without improving the environmental friendliness of production. The article analyzes the legislation of the Russian Federation and the practice of its application to identify mechanisms that promote sustainable development and eliminate barriers to the implementation of this concept in the mining industry. New technological solutions have been developed for mining enterprises of the Murmansk region, aimed at reducing aero-technogenic emissions, cleaning waste (mine) water, processing tailings of enrichment as man-made deposits, which allows both to minimize man-made environmental impacts and to increase the full use of mineral raw materials. Thus, the expediency of using the principles of “green growth” for the development of economic development policies in the Arctic is justified.

Flotation Process

There is a worldwide trend of increasing the share of extraction and processing of low-grade minerals, but their extraction and processing volumes are still low. There are several reasons for this: high mining and transportation costs, imperfect techniques and technological difficulties in enrichment and processing of refractory and low-quality minerals. Due to the depletion of reserves of easily beneficiated raw materials and to compensate for the growing shortage of high-quality minerals, the Russian mining industry development strategy provides for the involvement of new and unconventional types of deposits into production. Examples of such deposits are deposits of carbonaceous raw materials (black shale, refractory sulphide carbon-bearing ores, impactites, etc.) containing carbon of varying degrees of metamorphism. On the basis of the most modern mineralogical, physical, nuclear and chemical methods of research of composition, structure and properties of the carbonaceous raw materials at the micro- and nanolevel, the composition of the productive mineral matter, physical, chemical and thermodynamic laws of separation of valuable mineral components and the basic technological processes to obtain the finished product for valorization of the unconventional carbonaceous mineral raw materials were determined with maximum reliability. One of the possible reasons of difficulty of beneficiation of carbonaceous raw materials is the fine phenocrysts in graphite which can be solved by using the flotation process. Contrast of surface properties of minerals with similar technological properties can be increased by application of different energy effects (MEMI, MIO, microwave, electrochemical treatment etc.) at successive stages of raw material transformation, regulation of pulp conditioning conditions (duration and intensity of agitation, heat treatment of pulp) as well as by development and application of selective reagent regimes. The special feature of flotation as a method of extraction of noble and rare metals is the ability to extract valuable metals not only in their native free form, but also in close association with sulphides and carbon. Flotation with the use of intensifying influences made it possible to transfereven low-sized structures of noble and rare metals, which are not extracted by conventional methods of cyanidation, gravitation enrichment and amalgamation, into the concentrate. One of the ways to increase the efficiency of the flotation process is preliminary modification of the additive which is introduced in addition to the main reagents of the sinter - “carrier material”.
