Patio process - Wikipedia

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.

Silver processing - The metal and its alloys | Britannica

Silver processing - Silver processing - The metal and its alloys: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.

Roasting. Continued

Silver chloride is not decomposed by heat. 25. Iron perchloride, formed quite early in the roasting, is volatile, and some of it flies away, while another part, giving off chlorine, is reduced to proto-chloride, and this again, losing the remaining chlorine, takes oxygen from the air, and forms iron peroxide, which remains in the ore. 26.
