Hydrometallurgy Wikipedia
Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials [1] [2] Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy Hydrometallurgy is typically divided into three general areas: LeachingHistory Miners at the Tamarack mine in Copper Country, in 1905 The Old Copper Complex in North America has been radiometrically dated to 9500 BP—ie, about 7480 BCE—making it one of the oldest known examples of copper extraction in the world The earliest evidence of the coldhammering of native copper comes from the excavation at ÇayönüCopper extraction Wikipedia

Refining Wikipedia
Refining (also perhaps called by the mathematical term affining) is the process of purification of a (1) substance or a (2) formThe term is usually used of a natural resource that is almost in a usable form, but which is more useful in its pure form For instance, most types of natural petroleum will burn straight from the ground, but it will burn poorly andgold processing, preparation of the ore for use in various products For thousands of years the word gold has connoted something of beauty or value These images are derived from two properties of gold, its colour and its chemical stabilityThe colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation withGold processing | Refining, Smelting & Purifying | Britannica
Electrowinning Wikipedia
Electrowinning Electrorefining technology converting spent commercial nuclear fuel into metal Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching Electrorefining uses a similar process to remove impurities from a metalFive of the world’s most important precious metal refineries are located in Switzerland: Pamp, ArgorHeraeus, Metalor, Valcambi and Cendres Métaux Valcambi, which processes around 2,000 tons of precious metal annually, is by far the largest refinery Gold processing involves complex operations which include the use of old goldPrecious metal refining: Switzerland and worldwide Swiss Gold
Gold Wikipedia
Gold often occurs in free elemental ( native state ), as nuggets or grains, in rocks, veins, and alluvial deposits It occurs in a solid solution series with the native element silver (as in electrum ), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyriteAbstract The technique of smelting mined gold ore concentrates reported by Diodorus Siculus as being used in Egypt in the Second Century BC has been simulated in the laboratory A considerable degree of refining was found, comparable with that yielded by the medieval process of cementation with salt, and with a negligible loss of goldAncient Egyptian gold refining | Gold Bulletin
