Silver processing | Britannica
18-11-2019 · Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration,
Metalworking - Wikipedia
Brazing is a joining process in which a filler metal is melted and drawn into a capillary formed by the assembly of two or more work pieces. The filler metal reacts metallurgically with the workpiece(s) and solidifies in the capillary, forming a strong joint. Unlike welding, the work piece is not melted.

Silver mining - Wikipedia
Silver mining is the resource extraction of silver by mining. Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver).

Silver - Wikipedia
Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine".
Refining (metallurgy) - Wikipedia
In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a stone change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer.
Smelting - Wikipedia
It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a stone reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
