The Role of Arsenic in the Mining Industry

2015-5-14  [8] Arsenic can also be leached out of some metal ores by cyanide or acid rock drainage but can be captured and removed from wastewater before it is released into the environment. [12] Arsenic is also present in coal used to generate electricity. When coal is burned, ash is produced which contains most of the naturally occurring arsenic.

Arsenic: Will it take the shine off the red metal?

2020-8-5  Arsenic is a poisonous element found within minerals at many of the world’s copper mines. As a consequence of sulphide ore processing, arsenic is concentrated along with copper; this becomes more acute as the in-situ grade increases. The largest copper supply region in the world, Latin America, has high arsenic content in many of its ageing
