Ore processing consists of the following stages: Crushing and grinding of the ore. Addition of process water (generally decanted from the tailings pond) to form a slurry. Addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution. Addition of carbon to adsorb (attach) dissolved metals and remove

Silver processing-Refining, Alloying, Uses: 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
