Silver mining - Wikipedia
Silver mining is the resource extraction of silver by mining.. 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 (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver). As silver is often found in conjunction with

How to Refine Silver | Sapling
Mar 28, · When refining silver you want to make sure you do this outside where there is plenty of ventilation. Give yourself plenty of room in order to have a quicker dissolving reaction from the silver. Depending on how much silver you have to refine will depend on how many 5 gallon buckets you will need.
U.S. GEOLOGICAL SURVEY CIRCULAR 1196–N
The use of silver dates from the earliest historic records, and it was usually extracted by melting silver-bear-ing lead ore (ore containing argentiferous galena).
