Las Palmas vs Cobalt

Informations

Las Palmas (UK: , US: ; Spanish: [las ˈpalmas]), officially Las Palmas de Gran Canaria, is a city and capital of Gran Canaria island, in the Canary Islands, on the Atlantic Ocean. It is the capital (jointly with Santa Cruz de Tenerife), the most populous city in the autonomous community of the Canary Islands, and the ninth-largest city in Spain with a population of 383,308 in 2010. It is also the fifth-most populous urban area in Spain and (depending on sources) ninth- or tenth-most populous metropolitan area in Spain.Las Palmas is located in the northeastern part of the island of Gran Canaria, about 150 km (93 mi) off the Moroccan coast in the Atlantic Ocean. Las Palmas experiences a hot desert climate, offset by the local cooler Canary Current, with warm temperatures throughout the year.

It has an average annual temperature of 21.2 °C (70.2 °F). According to a study carried out by Thomas Whitmore, director of research on climatology at Syracuse University in the U.S., Las Palmas enjoys "the best climate in the world".The city was founded in 1478, and considered the de facto (without legal recognition) capital of the Canary Islands until the seventeenth century. It is the home of the Canarian Ministry of Presidency (shared in a four-year term with Santa Cruz de Tenerife), as well as half of the ministries and boards of the Canarian government, and the High Court of Justice of the Canary Islands.

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.
