Arsenic - Wikipedia
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and a

Arsenic - Deposits and Prices Institute for Rare Earths and Metals
Arsenic trichloride reacts with hydrogen to form hydrogen chloride and elemental arsenic. Previously, it was also produced by sublimation from solutions in liquid lead. The sulfur of the arsenic ores is bound by the lead in the form of lead (II) sulfide. The resulting purities of over 99,999 percent were insufficient for semiconductor applications.

Arsenic - USGS Publications Warehouse
Arsenic may be obtained from copper, gold, and lead smelter flue dust, as well as from roasting arsenopyrite, the most abundant ore mineral of arsenic. Arsenic has been recovered from orpiment and realgar in China, Peru, and the Philippines and from copper-gold ores in Chile, and arsenic was associated with gold occurrences in Canada.

Arsenic - Minerals Education Coalition
Description. Arsenic (As) is classed as a semi-metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur.
MoreGerman-Chilean consortium investigates new ways of reducing arsenic
As the world's largest copper exporter, Chile is encountering a growing number of sulfur-based ore layers containing toxic arsenic in its copper mines. Conven-tional strategies for separating and landfilling arsenic are proving limited in this area. The German-Chilean project team, led on the German side by the Fraunhofer Research

Sumerian Arsenic Copper and Tin Bronze Metallurgy (5300-1500
Copper was one of the first metals to be utilized since 8000 BC. Arsenic copper became popular due to its lower melting point and decreased metal porosity, allowing for the creation of longer metal blades. Tin bronze began appearing around 3500 BC, and its superior recyclability and malleability made it the favorite metal alloy until the prevalence of iron.

Arsenic What is arsenic? - NCDHHS
arsenic in fish/shellfish is in the organic form which is the less harmful form. Some seaweed may contain arsenic in inorganic forms that may be more harmful. Volcanic eruptions are another natural source of arsenic. Industrial processes such as mining and smelting of arsenic containing ores and burning coal may release arsenic to the environment.

Virginia Energy - Geology and Mineral Resources - Arsenic
Arsenic is a gray metal with the chemical symbol As. As a pure metal, arsenic is semi-metallic and very brittle. Arsenic reacts rapidly with air, tarnishing and oxidizing into arsenous oxide. When heated, arsenic sublimes forming ferrous sulfide. It is a strengthening alloy with other metals, although tends to be soft in pure form.
