Generally, the contents of As and Cu in copper concentrate are ~0.2% and ~25%, respectively; that is, the cumulative total of arsenic brought into copper smelting systems is estimated to be more than 56,000 tons every year (Nazari et al., 2016, Li et al., 2017a, Li et al., 2017b). Due to the small market capacity of arsenic-related products ...

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting ...

Copper anode slime (CAS) contains high concentrations of precious metals, particularly gold, which can reach up to 11 wt%. During copper anode electrorefining, 5–10 kg of CAS is generated per ton of copper cathode. Processing CAS is crucial for economic reasons, as gold significantly contributes to revenue for both miners and custom copper smelters. This …
