Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite, chlorargyrite, and galena.

Extracting the silver involves floatation, concentration, and leaching processes. The Wilfley Heavy-Duty Centrifugal pumps, in conjunction with its Waterless and Leakless Seal Technology, and abrasion-resistant materials offer a unbitable solution for those demanding conditions.
