Chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ ˌ r aɪ t,-k oʊ-/ [7] [8] KAL-kə-PY-ryte, -koh-) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS 2 and crystallizes in the tetragonal system.
Red plague is an accelerated corrosion of copper when plated with silver. After storage, damage or use in high-humidity environment, cuprous oxide forms on the surface of the parts. The corrosion is identifiable by presence of patches of brown-red powder deposit on the exposed copper. [1]
Green liquid with symbol Ar and atomic number 7. Makes a compound that is corrosive to copper when mixed with Galine and Sanite, and a compound that produces clouds when exposed to air when mixed with Regalite. The real element 7 is nitrogen; and Ar = argon. Atium Mistborn: Metal. Forms the body and power of the shard Ruin. If an Allomancer ...
Copper toxicity (or Copperiedus) is a type of metal poisoning caused by an excess of copper in the body. Copperiedus could occur from consuming excess copper salts, but most commonly it is the result of the genetic condition Wilson's disease and Menke's disease, which are associated with mismanaged transport and storage of copper ions.
Pure metallic copper produces a very dark red, opaque glass, which is sometimes used as a substitute for gold in the production of ruby-colored glass. Metallic gold , in very small concentrations (around 0.001%, or 10 ppm), produces a rich ruby-colored glass ("Ruby Gold" or "Rubino Oro"), while lower concentrations produces a less intense red ...
The bird flu outbreak has taken concerning turns, with more than 60 human cases confirmed. Experts outlined four signs that the virus is going in the wrong direction.
In 2001, an 18-year-old committed to a Texas boot camp operated by one of Slattery’s previous companies, Correctional Services Corp., came down with pneumonia and pleaded to see a doctor as he struggled to breathe.
Azurite or Azure spar [5]: 14 is a soft, deep-blue copper mineral produced by weathering of copper ore deposits. During the early 19th century, it was also known as chessylite, after the type locality at Chessy-les-Mines near Lyon, France. [3]
