Isotopic Ag–Cu–Pb record of silver circulation through 16th–18th
Except for a handful of data on native silver, the isotopic composition of silver ores is largely unknown. Native silver ores from Italy, Mexico, Canada, Russia, and Norway show ε 109 Ag variations of ∼5 parts per 10,000 (25–27). A major finding of our work is that a substantial proportion of American Ag has isotope compositions that can ...

Silver Ore – The Mining Processes that Transform Ore into Bullion
The first stage of mining silver involves the crushing the silver ore to about 1-1.5in diameter so as to make the ore porous for the extraction process. Once the ore is crushed it is then mixed with lime (about 3-5 lb. per ton) to create a conducive alkaline conditions for the extractions. The ore is then stacked onto impermeable pads made of ...
