Nickel Deposits Of Finland
The Finnish nickel deposits were found in the Pechengsky District, Petsamo area near the Barents Sea. Until the Paris Peace Treaties, 1947, this was the northernmost part of Finland. In 1934 it was estimated that the deposits contained over five million tons of nickel. In 1935, Canada, Canadian and France, French corporations began mining operations there. The nickel deposits were a lesser known reason for Allies of World War II, Allied and Nazi Germany, German interest in the area during World War II, as potentially of great importance for production of arms and munitions. Both the planned Franco-British support of Finland in the Winter War, and German occupation of Denmark and Norway (Operation Weserübung) were partly motivated by control of the nickel mines. During the period between the Winter War and Operation Barbarossa, the German invasion of the Soviet Union in 1941, there were disputes between Finland and the Soviet Union over mining rights in Petsamo. Finland refused to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nickel
Nickel is a chemical element with 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 classified a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
