Liquation - Wikipedia

The 16th-century process of separating copper and silver using liquation, described by Georg Agricola in his 1556 treatise De re metallica, remained almost unchanged until the 19th century when it was replaced by cheaper and more efficient processes such as sulphatization and eventually electrolytic methods.

Silver processing Britannica

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, and mercury. The mixing was accomplished by tethering mules to a central post on a paved patio (hence the name of the process) and compelling them to walk in a circle through the mixture.
