Palladium Mining, Techniques, Mines, Occurence, PGM, Metal

The mining of palladium is a very intricate process because of the fact that palladium is so spread out under the surface and in the mines and requires using mechanical extraction methods, which simplifies the process and makes it much easier to get down to the lower portions of the Earths crust. Since the upper portions have reserves thate depleted, miners have to dig deeper and

Silver processing The metal and its alloys Britannica

In order to obtain the lustre and corrosion resistance of silver on other metals and alloys, silver electroplating is practiced. Cyanide based baths aremonly employed. Because silver has the highest electrical conductivity of all metals, it is used in alloyed form for electrical contacts.

OverviewHistoryOre processingSee alsoFurther readingExternal links

Silver mining is the resource extraction of silver by mining.
Silver is found in a native form very rarely as nuggets, but morebined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite Ag2S, chlorargyrite horn silver, AgCl, and galena a leadore often containing significant amounts of silver. As silver is often found in conjunction with these or alloyed with other metals such as gold, it usually must be further extracted through amalgamati
