Copper-Arsenic Processing

Arsenic is the main impurity present in copper concentrates, and is predicted to be above penalty limits in 10% of all copper concentrates produced in 2015. The arsenic content in copper concentrates is expected to grow from ~80,000 tonnes/year in 2013, to ~165,000 tonnes/year in 2020. [Wood Mackenzie 2013].

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

2020-9-5 · Capturing arsenic in early stage processing has cost advantages compared to processing high arsenic waste. Due to the relatively low capture rate of standard copper sulphide processing methods such as flotation, it cannot be applied to high arsenic ores in isolation. Several processing methods exist, as seen
