Statistics and information on the worldwide supply of, demand for, and material flow of arsenic.
Arsenic (As) is a gray metal rarely encountered as a free element, but is widely distributed in minerals and ores that contain copper, iron, and lead. Arsenic may be obtained from copper, gold, and lead smelter flue dust as a byproduct, as well as from roasting arsenopyrite, the most abundant ore mineral of arsenic. Arsenic is often found in groundwater as a result of the natural weathering of rock and soil.
We are currently in the process of transitioning our datasets to the USGS ScienceBase platform to improve long-term accessibility, documentation, and version control. As part of that transition, we have temporarily paused public posting of our Minerals Yearbook (MYB) tables but will resume publication of them when the process is complete. Users subscribed to the automatic notification will be informed as each MYB becomes available. Thank you for your patience.
