arsenic sources from copper mine

Arsenic in Copper Concentrate

Mar 17, 2017 Tennantite and enargite as well as Freibergite are copper arsenic sulphide minerals that respond to flotation in a similar manner to other copper sulphides. As such, depression of these minerals would tend to result in depression of other copper sulphides. In this case arsenic comes Copper Arsenic Species called Enargite and Tennantite.

Arsenic pathways in Copper Mining Sustainability Issues

Arsenic is a naturally occurring element, however its presence in ore deposits can have production, environmental and human health implications. The mining industry’s approach to life-of-mine planning has improved significantly in recent decades and managing arsenic is not an exception.

The Role of Arsenic in the Mining Industry

Arsenic may also be obtained from copper, gold, and lead smelter flue dust as well as from roasting arsenopyrite, the most abundant ore mineral of arsenic. However, arsenic is not recovered from these sources but is rather disposed of in an environmentally safe manner. Arsenic

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

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
