As the most common source of mercury in nature, cinnabar has been mined for thousands of years, even as far back as the Neolithic Age. During the Roman Empire it was mined both as a pigment, and for its mercury content.: XLI. To produce liquid mercury (quicksilver), crushed cinnabar ore is roasted in rotary furnaces.Pure mercury separates from sulfur in this process and easily evaporates.
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 1554. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas.
