Abstract:
<p align="justify"> Silver is a natural solid with a crystalline stable structure and exhibits an abundance of 0.04 ppm (mg/kg) in the earth crust. Silver thus, like gold, is one of the chemical elements less abundant in nature. Only palladium, tellurium, platinum, ruthenium, rhodium, osmium, rhenium and iridium, present smaller geochemical distribution. However, because of its lower chemical reactivity, the metal presents a low representative in the mineral constitution. This review presents a synopsis of silver minerals (129 substances) as a contribution to the scientific knowledge of these substances. </p>
