Edmonton vs Cobalt

Informations

Edmonton ( (listen)) is the capital city of the Canadian province of Alberta. Edmonton is on the North Saskatchewan River and is the centre of the Edmonton Metropolitan Region, which is surrounded by Alberta's central region. The city anchors the north end of what Statistics Canada defines as the "Calgary–Edmonton Corridor".The city had a population of 932,546 in 2016, making it Alberta's second-largest city and Canada's fifth-largest municipality. Edmonton's 2019 municipal census subsequently recorded a population of 972,223. Also in 2016, Edmonton had a metropolitan population of 1,321,426, making it the sixth-largest census metropolitan area (CMA) in Canada. Edmonton is North America's northernmost metropolitan area with a population over one million. A resident of Edmonton is known as an Edmontonian.Edmonton's historic growth has been facilitated through the absorption of five adjacent urban municipalities (Strathcona, North Edmonton, West Edmonton, Beverly and Jasper Place) in addition to a series of annexations through 1982, and the annexation of 8,260 ha (82.

6 km2) of land from Leduc County and the City of Beaumont on January 1, 2019. Known as the "Gateway to the North", the city is a staging point for large-scale oil sands projects occurring in northern Alberta and large-scale diamond mining operations in the Northwest Territories.Edmonton is a cultural, governmental and educational centre. It hosts a year-round slate of festivals, reflected in the nickname "Canada's Festival City". It is home to North America's largest mall, West Edmonton Mall (the world's largest mall from 1981 until 2004), and Fort Edmonton Park, Canada's largest living history museum.

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in 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, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought to be due to the known metal bismuth. Miners had long used the name kobold ore (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 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), and this was ultimately named for the kobold. Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more usually produced as a by-product of copper and nickel mining.

The copper belt in the Democratic Republic of the Congo (DRC) and Zambia yields most of the global cobalt production. World production in 2016 was 116,000 metric tons (114,000 long tons; 128,000 short tons) (according to Natural Resources Canada), and the DRC alone accounted for more than 50%.Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. The compounds cobalt silicate and cobalt(II) aluminate (CoAl2O4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays. Cobalt is the active center of a group of coenzymes called cobalamins. Vitamin B12, the best-known example of the type, is an essential vitamin for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae, and fungi.
