Regions Of Finland
Finland is divided into 19 regions (; ) which are governed by regional councils that serve as forums of cooperation for the Municipalities of Finland, municipalities of each region. The councils are composed of delegates from the municipal councils. The main tasks of regional councils are regional planning, the development of enterprises, and education. Between 2004 and 2012, the regional council of Kainuu was elected via popular elections as part of an experimental regional administration. In 2022, new Wellbeing services counties of Finland, Wellbeing services counties were established as part of a health care and social services reform. The wellbeing services counties follow the regional borders, and are governed by directly elected county councils.

Kainuu
Kainuu (), also historically known as Cajania (), is one of the 19 regions of Finland (''maakunta'' / ''landskap''). Kainuu borders the regions of North Ostrobothnia, North Savo and North Karelia. In the east, it also borders Russia (Republic of Karelia). Culturally Kainuu is part of larger Eastern-Finnish cultural heritage. The dialect of Kainuu resembles Savonian and Karelian dialects. Geography Boreal forest makes up most of the biome in Kainuu. The forest in Kainuu mostly consists of birches, pines and spruces. The atypical regional geography and landscape consist of lakes, hills and vast uninhabited forest areas. The largest lake in the region is the Oulujärvi (928.09 km2), one of the largest lakes in Finland. Its shorelines, open waters and islands in Kainuu belong to the municipalities of Paltamo and Kajaani. The highest point in Kainuu is the Iso Tuomivaara (385 m), located in the municipality of Hyrynsalmi. The regional climate is continental. The three mos ...

Finland
Finland, officially the Republic of Finland, is a Nordic country in Northern Europe. It borders Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland to the south, opposite Estonia. Finland has a population of 5.6 million. Its capital and largest city is Helsinki. The majority of the population are Finns, ethnic Finns. The official languages are Finnish language, Finnish and Swedish language, Swedish; 84.1 percent of the population speak the first as their mother tongue and 5.1 percent the latter. Finland's climate varies from humid continental climate, humid continental in the south to boreal climate, boreal in the north. The land cover is predominantly boreal forest biome, with List of lakes of Finland, more than 180,000 recorded lakes. Finland was first settled around 9000 BC after the Last Glacial Period, last Ice Age. During the Stone Age, various cultures emerged, distinguished by differen ...

Nickel
Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Zinc
Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the second most abundant trace metal in humans after iron, an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt
Cobalt is a chemical element; it has Symbol (chemistry), symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal. Cobalt-based blue pigments (cobalt blue) have been used since antiquity for jewelry and paints, and to impart a distinctive blue tint to glass. The color was long thought to be due to the metal bismuth. Miners had long used the name ''kobold ore'' (German language, German for ''goblin ore'') for some of the blue pigment-producing minerals. They were so named because they were poor in known metals and gave off poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), which was ultimately named for the ''kobold''. Today, some cobalt is produced sp ...

Talvivaara Mining Company
Ahtium (known until 2017 as the Talvivaara Mining Company; ) was a Finnish mining company that operated the Talvivaara nickel mine from the company's establishment in 2004 until the mining business was sold to the state-owned in 2015. Formerly listed on the London and Helsinki Stock Exchanges, the company was a constituent of the OMXH25 index. Its mining business, Talvivaara Sotkamo, went bankrupt in November 2014, and it is bound for liquidation, with at least 98% of equity lost, and €1.4 million debt outstanding. The mine had suffered several leaks of toxic metal-contaminated tailings, which had threatened local waterways. Members of the management were charged with criminal environmental offenses. There has been considerable government involvement, with the Government of Finland being the largest single owner through their investment company Solidium. In 2015, the newly established government-owned corporation Terrafame bought the mining business of Talvivaara. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
