The patio process is a process for extracting silver from ore. Smelting, or refining, is most often necessary because silver does not very frequently occur in the nature by itself as a native element mineral like some metals nobler than the redox couple 2  H + 2  e ⇌ H 2 (gold, mercury,). Instead, it is made up of a larger ore body. Thus, smelting, or refining, is necessary to reduce the Ag cation into
