ACANTHITE/ARGENTITE (Silver Sulfide)

Acanthite is the most important silver ore next to galena.Actually there is an argument to be made that acanthite could be the most important silver ore. Galena is a lead ore that often contains enough silver (usually about 1%) that when it is processed for its lead content the by-product silver supplies the majority of the world's needs.
