Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.

Ancient Metallurgy - University of California, San Diego
2021-3-27 Unlike gold, silver rarely occurs in a pure form in a sufficient quantity to be useful. Usually it has been procured by smelting other ores, of which it can be thought of as almost a by-product. In antiquity a common ore used to produce silver was galena, or lead sulfide, although it appears that lead carbonate (cerussite) was also used.
