Arsenic: Will it take the shine off the red metal? | McKinsey
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 ...
