Where is silver mainly found?
It also is mined from the minerals acanthite (silver sulfide) and stephanite. Silver also is found in the common minerals chlorargyrite (silver chloride) and polybasite. Silver is mined in many countries, but most comes from the USA, Canada, Mexico, Peru and Bolivia.
Is silver used in batteries?
Batteries are, in reality, very simple pieces of engineering. They all contain three key components – two electrodes and an electrolyte material. In the Voltaic Pile, the electrodes were silver and zinc, with the brine acting as the electrolyte. The critical part of any battery is that the two electrodes are different.
