In addition, the majority of silver today is obtained from lead–zinc concentrates and may be extracted with either pyrometallurgical or hydrometallurgical techniques (Holloway et al., 2004). However, a high oxidation potential, often required to attack the sulfide minerals (Ekinci et al., 1998), favors sulfate ion formation, which ...

Zinc Copper Lead Gold & Silver Concentrate Marketing

For example, if you ship a lead-copper concentrate to a lead smelter, you will receive about 30 cents a pound less for the copper, while if this same lead-copper concentrate is shipped to a typical copper plant, you will be paid for only half the lead and will get about 40 cents a pound less for that lead.
