separation of copper by flotation

Selective Removal of Arsenic from Copper Concentrates

There is currently no widely accepted industrial process that specifically aims to separate copper and arsenic minerals by flotation. Arsenic bearing minerals such as enargite (Cu 3 AsS 4) are a rich source of copper. Enargite contains 48 wt% of copper, compared to chalcopyrite (CuFS 2) which contains 34 wt% copper.
