Metalurgy is the science and technology of metals.
Yes, one common method to separate silver from other metals is through a process called electrolysis. In this process, an electric current is passed through a solution containing the silver and other metals, causing the silver to be deposited onto the cathode while the other metals remain in the solution. This allows for the separation of the silver from the other metals.
When gold is refined, the process is called gold refining or purification. It involves removing impurities, base metals, and other elements from raw or recycled gold to achieve high purity—usually 99.9% or higher. Refiners often use methods like the Miller process (chlorine gas) or the Wohlwill process (electrolysis) to separate pure gold from other materials, resulting in bullion-grade gold suitable for coins, bars, or industrial use.
Ores are minerals from which metals and nonmetals can be extracted in usable amounts through processes like mining and refining. These ores are the primary sources of various elements used in industry and technology.
Silver is usually refined through a process called electrolysis. In this process, an electric current is passed through a solution containing silver, causing the silver to be extracted and deposited onto a cathode. This results in purer silver being obtained.
Metallurgy is the art of working metals, comprehending the whole process of separating them from other matters in the ore, smelting, refining, and parting them; sometimes, in a narrower sense, only the process of extracting metals from their ores.
Simply because - their rarity, and process of refining makes them expensive metals. Owning gold or platinum jewellery implies the wearer has an amount of wealth.
Preparation of very pure metals.
Electrolysis... Some people say electro refining

The purpose of the refining process is to remove impurities and contaminants from raw materials or substances, such as petroleum, metals, or chemicals. This process helps to improve the quality, purity, and usefulness of the final product. Refining also aims to ensure compliance with industry standards and regulations.

One highly recommended book on refining precious metals is "Refining Precious Metal Wastes" by C.M. Hoke. It provides detailed information on various refining techniques, processes, and equipment needed for refining gold, silver, platinum, and other precious metals. It is often considered a comprehensive guide for individuals and businesses involved in precious metal refining.
A lab tech in smelting and refining of non-ferrous metals may be responsible for conducting chemical analyses on samples, monitoring process parameters, ensuring quality control of the final product, and collaborating with production personnel to troubleshoot any issues that arise during the process. They play a critical role in maintaining the efficiency and quality of the smelting and refining operations.
A cupel used in metal refining is typically called a "cupel." It is a crucible-like vessel made of porous material, often used in processes such as fire assay to separate precious metals like gold and silver from impurities. During the process, the cupel absorbs the lead and other base metals, allowing the precious metals to be left behind for collection.
It is called smelting
Smelting
Turning scrap into gold can be accomplished through the process of precious metal refining. This process takes metals and makes them purer. Alchemy is the medieval magic that supposedly turned scrap into gold.
