These New World mines, much richer in silver, resulted in the rise of South and Central America as the largest silver-producing areas in the world. For the recovery of New World silver, the Patio process was employed. Silver-bearing ore was ground and then mixed with salt, roasted copper ore

Silver is commonly extracted from ore by smelting or chemical leaching. Ore treatment by mercury amalgamation, such as in the patio process or pan amalgamation was widely used through the 1800s, but is seldom used today. Silver is also produced during the electrolytic refining of copper and by application of the Parkes processon lead metal obtained from lead ores that contain small amounts of silver. Commercial grade fine silver i

The patio process is a process for extracting silver from ore. The process was invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. The patio process was the first process to use mercury amalgamation to recover silver from ore. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas. Other amalgamation processes were later developed, importantly the pan amalgamation process, and its variant, the Washoe process. The silver separation process generall

Also, the recovery of silver minerals occurring in a lead, zinc sulfide ore is efficiently accomplished using Flowsheet #2. The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate. Over-grinding of silver minerals is detrimental to efficient flotation
