Silver is found embedded in several different minerals, namely copper, zinc and lead, and the refining process varies depending on the source. Silver derived from copper and its derivatives, including copper sulfide, requires different handling and refining techniques than silver minerals taken from zinc deposits and lead sources. These metals have different physical properties, which accounts for the different methods needed for proper extraction.
