    Arsenic | Minerals Education Coalition

    Arsenic occurs in pure form only in small deposits. It occurs in many minerals, and usually is obtained as a by-product from the mining, processing and refining of other minerals. Common arsenic-bearing minerals include arsenopyrite, conichalcite, enargite, lollingite (iron arsenide), olivenite and orpiment.Arsenic - Wikipedia,Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the second most commonly used semiconductor after doped silicon. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, andThe Role of Arsenic in the Mining Industry,? The rate of arsenic release from sulfide minerals can be accelerated by mining activities, which expose the minerals to weathering processes during excavation. Also, arsenic can be mobilized by weathering of outdoor stored waste byproducts produced during the subsequent metal value recovery process.
