Krasnoyarsk Krai
Krasnoyarsk Krai ( rus, Красноя́рский край, r=Krasnoyarskiy kray, p=krəsnɐˈjarskʲɪj ˈkraj) is a federal subject of Russia (a krai), with its administrative center in the city of Krasnoyarsk, the third-largest city in Siberia (after Novosibirsk and Omsk). Comprising half of the Siberian Federal District, Krasnoyarsk Krai is the largest krai in the Russian Federation, the second largest federal subject (after neighboring Sakha) and the third largest subnational governing body by area in the world, after Sakha and the Australian state of Western Australia. The krai covers an area of , which is nearly one quarter the size of the entire country of Canada (the next-largest country in the world after Russia), constituting roughly 13% of the Russian Federation's total area and containing a population of 2,828,187 (more than a third of them in the city of Krasnoyarsk), or just under 2% of its population, per the 2010 Census. Geography The krai lies in the middl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) 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 metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...
