the patio process is a process for extracting silver from ore. the process, which uses mercury amalgamation to recover silver from ore, was reportedly invented by bartolomé de medina in pachuca, mexico, in 54. it replaced smelting as the primary method of extracting silver from ore at spanish colonies in the americas. although some knowledge of amalgamation techniques were likely known since the classical era, it was in the new world that it was first used on a large industrial scale. other amalga · text under ccbysa license
