The paper presents a proposal for methodology of designation of the key, strategic and critical minerals, important for the mineral security of Poland. The authors proposed a comprehensive methodology for analysis of 148 individual minerals. When determining the key minerals, a criterion of average value of their annual consumption in Poland in the last decade (2009-2018) was adopted. This approach also regards to the general tendency of consumption of a given mineral and the net import reliance index. To determine strategic minerals, a two-stage analysis was performed, i.e. the identification of potentially strategic minerals that are indispensable for the sectors defined as crucial for the country’s economic security (based on an expert assessment), and – from among them – establishment of the list of strategic minerals on the basis of criteria of the average consumption value in recent years and the net imports reliance. For the identification of critical minerals, the methodology developed for the European Union with some significant modifications was adopted: all the minerals previously classified as key and/or strategic were granted the status of high economic importance in Poland, with disregarding of EU’s evaluation of the value of economic importance (EI) indicator. The second EU index – the supply risk index (SR) – for the determination of the critical minerals for Poland – was slightly reduced from 1.0 to 0.9. Based on the analysis conducted, three lists comprising 42 key, 24 strategic and 17 critical minerals indispensable for the Polish economy development were proposed. Identification of these minerals is of fundamental importance for further works on the Mineral Policy of Poland.

Odpady sprzętu elektrycznego i elektronicznego są źródłem m.in. glinu, żelaza (surowce strategiczne), miedzi, srebra (surowiec deficytowy), magnezu, kobaltu i antymonu (surowce krytyczne) oraz kadmu, stopów metali, a także tworzyw sztucznych (polipropylen, akrylonitryl-butadien-styren, polistyren i teflon). Stale postępujący rozwój technologiczny w zakresie sprzętu elektrycznego i elektronicznego powoduje u potencjalnych użytkowników chęć posiadania sprzętu nowej generacji. Naturalną konsekwencją tej prawidłowości jest wzrost ilości wytwarzanych odpadów zużytego sprzętu elektrycznego i elektronicznego (ZSEE).

The waste management of waste electrical and electronic equipment are the source of metals, for example: aluminium, iron (strategic raw materials), copper, silver (deficit raw material) magnesium, cobalt, antimony (critical raw materials) and cadmium and alloys, and plastics (for example: polypropylene, acrylonitrile-butadiene-styrene, polystyrene and teflon). Constant technological development in the field of electrical and electronic equipment causes potential users to desire newer generation of hardware. The natural consequence of this regularity is to increase the amount of waste of electrical and electronic equipment (WEEE).

Comprehensive and harmonious economic development of each country depends on the availability of raw materials, in particular mineral deposits, necessary for the functioning of the various industries that produce the substances and equipment required to meet the needs of the population, and for the efficient operation of agriculture and transport. The identification of raw materials, which are important for the country, is the basis of mineral policy and strategy. Diverse conditions of production of mineral raw materials result in their division into groups of different importance for the national economy. In Poland, three independent proposals for determining economically important mineral raw materials were developed. Despite their intuitive, similar approaches, various raw materials were identified as pivotal, strategic and critical. We would like to clarify their definitions: Pivotal raw materials – essential for the proper functioning of the economy and satisfying the needs of the society, those whose supply must be assured; Strategic raw materials - not sufficiently (at least 90%) supplied from domestic sources, or whose opportunities for permanent supply are limited or threatened (including the raw materials necessary for the development of innovative technologies); Critical raw materials - those whose chance of gaining (from both primary and secondary sources) is of high risk and their substitutability is low (in particular raw materials on the EU Critical List). There are 27 pivotal raw materials, especially important for the Polish economy, which are distinguished by the importance of raw materials and the importance of the substitution of raw materials. The list of strategic raw materials counts 36 items and includes a number of pivotal raw materials, important for the economy but being deficient in Poland. Eighteen mineral raw materials were considered critical. Depending on the changing, widely understood market conditions, such lists should be reviewed and updated at least every 5 years.

In 2008 Committee on Critical Mineral Impacts of the U.S. Economy, presented a definition of strategic raw materials, which was also adopted by the countries of the European Union. A group of strategic raw materials includes 12 minerals/materials with a very critical economic importance and specific conditions related to the criticality and risk of shortage of supply. The risk of the shortage of supply is mainly due to a limited number of sources of origin. These are: rhenium, tellurium, iron, aluminum, bauxite, magnesite, molybdenum, manganese, vanadium, zinc, nickel and chromium. The attention is put on the raw materials used in large quantities in the key industries (iron, aluminum) and the strategic raw materials which include among others: traditional ingredients of alloy steel (vanadium, chromium, manganese, molybdenum). The above list of 12 strategic raw materials is a proposal, which can be modified as a result of the reduction of strategic raw materials resources in European countries. The strategic raw materials are found in temperate locations in the world and have few substitutes. The analysis of the literature on identified technologies has showed that the most recognizable way to enrich the specific raw materials is by processing their ores, which are the carriers of many metals. The ore is processed to improve their chemical composition, to standardize their chemical and physico-chemical properties, to ensure the appropriate sizes of the ore pieces. Since the mined ores are mostly not suitable for direct processing, an important process is multi-enrichment. The enrichment of ores can be divided into: mechanical and chemical enrichment. The process of ore processing was applied to the following materials: rhenium, iron, molybdenum, manganese, vanadium, zinc, nickel and chromium. A comprehensive assessment of mineral potential of the European Union countries and the so-called identification of strategic raw materials a priority of the EU raw materials policy.

The paper presents the characteristics of types, occurrence and distribution of the ocean polymetallic deposits: polymetallic nodules, cobalt-rich ferromanganese crusts, seafloor massive sulphides and metalliferous clays. Possibility of extraction of critical raw materials (for the EU) and strategic raw materials (according the OECD report) from the ocean polymetallic deposits is indicated. Polymetallic nodules are the most recognized type of ocean polymetallic deposits, abundant mostly in abyssal basins at the depths of3500-6000 m b.s.l. The most important practical metals from the polymetallic nodules are: Fe, Mn (280 000-320 000 ppm), Ni (11 000-14 000 ppm), Co (2100 ppm), Cu (9500-13 000 ppm), Mo and rare earth elements (REE). Cobalt-rich ferromanganese crusts, which are laminatedferromanganese clusters occurring at a depth interval between 400-4000 m b.s.l., can have a prospective significance for the extraction of critical raw materials. They are found on the seamounts where seafloor currents have swept the rocky bottom clear of sediment. They contain large amounts of metals: Mn, Co, Ti, Pt, Te, Mo and Zr. The key factor determining the profitability of the crust mining will be cobalt extraction. However, profitability may increase if nickel, tellurium or REE would be recovered at the same time. The analyses show that the seafloor massive sulphides would be of great importance, as they are the potential source of gold, platinum, silver, copper, zinc and lead. Extraction ofthese deposits is associated with the smallest area ofexploitation and depth ofoccurrence (between 1500-3700 m b.s.l.) which can significantly facilitate commencing of mining operations. Their commercial extraction could begin in the next few years, provided a high concentration of gold and metals in the location near the coast, and a depth below 2000 m b.s.l. Metalliferous clays, which are the deposits enriched in manganese oxides or hydroxides and sulphides or iron, could become an important prospective source of rare earth elements. This is confirmed by a study in two regions: eastern South and central North Pacific. Prospective possibilities of mining the ocean polymetallic deposits increased due to a high concentration ofMn, Ni, Cu, Co, Pt and REE (La, Ce, Nd, Yb, Eu). REE recovery particularly increases the economic value of these deposits. Mining of the ocean polymetallic deposits would meet many technological difficulties and should be preceded by detailed environmental studies.
