Role of climate and geography in arsenic mobility and risk …
Arsenic (As) is a common contaminant at historical mining operations due to its association with gold and other metals and is often found in dust exposed on abandoned roasting equipment, or in geochemically transformed minerals within downstream media or dissolved in runoff (e.g., Haffert and Craw, 2008, 2009).

Only about 5% of arsenic consumption is of the metallic element. Most of this is used to alloy (mix) arsenic with lead, copper, or other metals for specific uses. As a metalloid, arsenic is a semiconductor, like silicon. This means it conducts some electricity like a metal, but not all the electricity a true conductor like copper would conduct.

Why gold loves arsenic
They found that when the minerals are enriched with arsenic, gold can enter mineral structural sites by directly binding to arsenic, forming, chemically speaking, Au (2+) and As (1-) bonds. This process allows gold to be stabilized in the mineral. However, when the arsenic concentration is low, gold doesn't enter the mineral structure but ...
