Our access to easily extractable copper is gradually diminishing as demands for copper continues to grow worldwide. To meet these demands, non-traditional, metallurgically challenging deposits are expected to become more prevalent, thereby forcing us to deal with more complex, and lower-grade ores containing higher levels of impurities. Arsenic-challenged deposits is a concern for the copper mining industry as arsenic produces hazardous fumes and oxide dusts during the smelting process. Smelting with arsenic therefore poses a significant risk to the health of the workers and to the environment. Safe removal and disposal of stabilized arsenic is often challenging and costly. Fines and penalties are set for arsenic concentrations exceeding 0.2%, while ores past 0.5% arsenic concentrations are rejected by smelters. The mining industry has developed
