Ore processing. Once removed from the mine, silver-containing ore is crushed (commutation) into a fine powder to expose individual grains to chemical processing.As a byproduct of mining of lead and copper, silver ores are often purified by froth flotation.After froth flotation, silver is extracted by a cyanide process, akin to technology used for gold extraction.

Almost all metals can form amalgams with mercury, a notable exception being iron. Silver-mercury amalgams are important in dentistry, and gold-mercury amalgam is used in the extraction of gold from ore. Mercury has been used in the gold and silver mining methods because of the convenience and ease with which mercury will amalgamate with them.

Amalgamation is based on the property of quicksilver to extract the silver from finely-pulverized ore and collect it in the form of an amalgam. When the rock has been separated from the amalgam by a washing operation, the quicksilver is recovered by distillation in an iron retort, and the remaining crude retortsilver melted into bars and ...

Cinnabar (/ ˈ s ɪ n ə ˌ b ɑːr /) or cinnabarite (/ s ɪ n ə ˈ b ɑːr aɪ t /), from the Ancient Greek: κιννάβαρι (kinnabari), is the bright scarlet to -red form of mercury(II) sulfide (HgS). It is the most common source ore for refining elemental mercury, and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments.

Metals commonly alloyed with gold for jewelry purposes include: silver, copper, nickel, iron, zinc, tin, manganese, cadmium, and titanium. In addition to enhancing gold's strength, alloying changes some of its other properties, too. For example, some gold alloys stain skin or cause allergic reactions.

Tailings and slimes contained a considerable amount of gold, silver sulphurets, and quicksilver. Because silver was more difficult to recover than gold, mills treating Comstock silver ore routinely missed between 25% and 35% of the ore's assay value. Bodie's mills, handling ore higher in gold content, missed only about 10% to 20% of the values.

Three drag stones, chained to a post in the center of the milling area, were rotated by hand or mule. The drag stones crushed the ore into a fine powder and water was added until a thick slurry was produced.
