Mispickel, or arsenopyrite, FeAsS, is among the most common of arsenic-bearing minerals; others are realgar, As 4 S 4; orpiment, As 2 S 3; loellingite, FeAs 2; and enargite, Cu 3 AsS 4. Arsenic oxide is also common.
The most common arsenic-containing mineral is arsenopyrite. Others include realgar, orpiment and enargite. Most arsenic is produced as a by-product of copper and lead refining.
Arsenic could be dangerous and beneficial to humans and in other applications, it depends on what it’s being used for. Below, we would take a look at few uses of Arsenic in the modern world. 1. Rat poison/Insecticide. Arsenic is a very effective poison and insecticide killer for rats and insects respectively.
The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III–V compound semiconductor gallium arsenide.
Arsenic is used industrially as an alloying agent, as well as in the processing of glass, pigments, textiles, paper, metal adhesives, wood preservatives and ammunition. Arsenic is also used in the hide tanning process and, to a limited extent, in pesticides, feed additives and pharmaceuticals.
Arsenic is sometimes alloyed with lead to form a harder, more durable metal. Some areas of use include car batteries and bullets. Until recently, arsenic was commonly used in glassmaking.
Arsenic and Pyrotechnics: Arsenic compounds find use in fireworks and pyrotechnics to produce white and yellow flames. Natural Arsenic Removal: Natural processes, such as microbial activity in groundwater and adsorption onto iron minerals, help reduce arsenic levels in contaminated water sources.
Uses. Arsenic is used as a doping agent in solid-state devices. Gallium arsenide is used in lasers which convert electricity into coherent light. Arsenic is used pyrotechny, hardening and improving the sphericity of shot, and in bronzing. Arsenic compounds are used as insecticides and in other poisons.
If ever there was an element that epitomizes the notion that chemicals might be good or bad depending on their use, arsenic must be it. Katherine Haxton explains why.
Today, the most important use of arsenic is in the preservation of wood. It is used in the form of a compound called chromated copper arsenate (CCA). CCA accounts for about 90 percent of all the arsenic used in the United States. It is added to wood used to build houses and other wooden structures.
