In Chile, the world's largest copper producer, most of the copper is obtained from sulfide ores [ 5][ 6]. Since copper sulfide ores present impurities, several purification steps are carried out to obtain a high-purity copper product. Figure 1 shows a simplified representation of copper production from sulfide minerals.
