The Role of Arsenic in the Mining Industry

Arsenic in the mining industry . Atmospheric arsenic emissions from copper smelting represent the largest contribution of arsenic from the mining and metals industry by far and have been the focus of pollution control technologies and increasingly stringent regulations. [8] Arsenic can also be leached out of some metal ores by cyanide or acid rock drainage

Arsenic Mining | Processing Equipment | Flow Chart | Cases ...

Relation to Mining Arsenic metal very rarely occurs in its pure form in nature. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur. Several other, less-common minerals contain arsenic, including orpiment, realgar, and enargite, which are arsenic sulfides. Most arsenic is obtained not from an ore mineral of arsenic, but as a by-product in the treatment of gold, silver, copper, and other metal ores. Environmental laws require that arsenic …

Site Profile - Arsenic Mine (RV4) - EPA OSC Response

the Site is a location of a former arsenic mine. Historic mining operations occurred in the mid-1800’s through 1918. At first miners believed that they had found a silver mine based upon the coloring of the mineral until it was sent out for analytical which determined that the mineral was actually arsenopyrite. Later mining operations were conducted for the arsenopyrite. On-site …
