Iron ore in significant quantities has been found in only four areas in arctic Europe. No deposits are known in arctic Asia or in the arctic islands of the eastern hemisphere. The largest iron-bearing area is in Swedish Lapland of which the total known reserves, mainly magnetite and hematite, are estimated at 2413 million metric tons, with an average iron content of over 63 per cent, or a ferric weight of about 1532 million tons. The greater part of this ore requires no concentration before use. There is a deposit of about 1000 million tons in Sør-Varanger in north Norway, with a low iron content, while the deposit at Yena in Kol'skiy Poluostrov (Kola peninsula) is estimated at nearly 850 million tons of ore with an iron content of 23 to 48 per cent, and like the Varanger ore requires concentration. A deposit with an iron content of 30 to 40 per cent has been investigated recently at Kolari in north-west Finland, but it is not yet worked.

Early Source

The use of iron-bearing sands such as those of the Black Sea has often been thought of as an early source of iron ore by archaeo-metallurgists. Indeed Japan was an avid user of such material as late as the 19th century, and its use was being considered by the Turkish authorities in 1975.The black sands of the south side of the Black Sea are very extensive, and obvious to the layman because of their unusual nature. They are also highly magnetic and quite a high proportion can be picked up with the aid of a small permanent magnet. On two occasions samples were taken and examined for their iron content and to see how reducible they were, i.e. how easy it would be for early smiths to use them. The analysis of two batches is given in Table 1. The first sample was taken from near Kirazlik, which is 42 km. west of Trabzon, and the second from sites extending from 4 km. west of Ordu to 10 km. west of Ünye. It is clear that there is not much difference in the composition from the two sites which are about 100 km. apart.

Iron Ore Concentrate

The work deals with examination of the influence of the ratio between iron ore concentrate and iron ore on quality of produced iron ore sinter. One of the possibilities to increase iron content in sinter is the modification of raw materials ratio, when iron ore materials are added into sintering mixture. If the ratio is in favor of iron ore sinter, iron content in resulting sintering mixture will be lower. If the ratio is in favor of iron ore concentrate and recycled materials, which is more finegrained, a proportion of a fraction under 0.5 mm will increase, charge permeability property will be reduced, sintering band performance will decrease and an occurrence of solid particulate matter in product of sintering process will rise. The sintering mixture permeability can be optimized by increase of fuel content in charge or increase of sinter charge moisture. A change in ratio between concentrate and iron ore has been experimentally studied. An influence of sintering mixture grain size composition, a charge grains shape on quality and phase composition on quality of the produced iron sinter has been studied.

Meaningful Role

In the Arctic, environmental conflicts over land use and the exploitation of natural resources cast shadows over communities. Artists’ and art educators’ responses can play a meaningful role in resisting harmful developments. Emerging artistic and pedagogical interventions follow principles of socially and environmentally engaged art and art education. This visual essay describes a contemporary art event that opposed plans for an iron ore mine next to Pallas-Yllästunturi National Park in Finnish Lapland. An art-based action-research strategy was used to develop resources for communities in conflict. It focuses on describing the cyclical nature of art interventions. Analyses of activities show that art-based resources in environmental battles can foster cultural resilience, impact values, enhance hope and allow for campaigning that uses art to communicate environmental concerns. Further research into artistic interventions that open dialogue between parties in conflict is required.

The Arctic Region

The purpose of the article is to identify regional features of the Arctic States of the Eastern hemisphere. The Arctic region has enormous geopolitical and economic potential, and in the twenty-first century it is becoming one of the main objects of conflict of interests of the leading powers of the modern world. In their research, the authors used experimental-theoretical methods, as well as system analysis, logical and historical methods. The results of the analysis of the literature used, actual data, and research searches have shown that the key element in determining the region is its borders. There are many definitions of the Arctic, but due to the Northern features, none of them fully corresponds to the tasks of state regulation of territories. Along with the General assessment of the region and space, the article analyzes in detail various approaches to determining the borders of the Arctic region of all the countries participating in the Eastern hemisphere: Denmark, Russia, Finland, Sweden, and Iceland. A retrospective analysis of the existing definitions for a wide range is carried out. The conclusions summarize that among the Arctic countries, the astronomical approach in combination with the administrative and political definitions of the participating countries themselves prevails, which begins to form trends towards changing approaches to the Arctic as a whole.

<p>The species <em>Scolelepis finmarchicus</em> sp. nov. is described from the Norwegian and Barents Seas along the northern Norwegian coast and Kola peninsula. The occurrence of this species in the Kola Bay could be seen as a sign of climate warming in the area. Taxonomic issues existing in the genus <em>Scolelepis</em> within the area along the Norwegian coast and in the Barents Sea are briefly touched upon. Seven species belonging to <em>Scolelepis</em> have recently been recorded from the Atlantic sector of the Arctic. <em>Scolelepis</em> (<em>S</em>.) <em>matsugae</em> Sikorski, 1994 is newly synonymized with <em>S</em>. (<em>S</em>.) <em>laonicola</em> (Tzetlin, 1985). This article provides a brief review of <em>Scolelepis</em> together with an identification key for the genus from the Atlantic sector of the Arctic</p>
