Gold parting is the separating of gold from and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called the advent of coinage, methods had to be invented to
Silver is similar in its physical and chemical properties to its two vertical neighbours in group 11 of the periodic table, copper and 47 electrons are arranged in the configuration [Kr]4d 10 5s 1, similarly to copper ([Ar]3d 10 4s 1) and gold ([Xe]4f 14 5d 10 6s 1); group 11 is one of the few groups in the dblock which has a completely consistent set of electron configurations.

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 lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000
ANTAM''s main gold and silver production is sourced from its underground gold mines at Pongkor, West Java and Cibaliung, Banten. Indications of gold deposits at Pongkor were discovered by ANTAM''s Geology Unit in 1981, and production commenced in May 1994 after ANTAM secured the mining license in 1992. The Cibaliung gold mine was acquired in 2009 from an Australian company, Arc Exploration
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it
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). As silver is often found in conjunction with
