One of the earliest methods for extracting gold, salt cementation, was perfected through the Iron Age. When the Lydian Empire was standardizing the purity of the gold and silver they were using for the world's earliest coinage, this was the method they relied on. When mined, gold is commonly merged with silver as an alloy called electrum.

concentration of gold and chemical separations are usually necessary to avoid a matrix effect. Tri-iso-octylamine (4) has been used for extraction of gold from hydrochloric or hydrobromic acid media with direct measurement of the absorbance of the organic phase without following the stripping step. Pohlandt has reported the effectiveness of

Chemical compounds of gold include potassium dicyanoaurate, K [Au (CN) 2 ], used in gold electroplating baths, and chloroauric acid, HAuCl 4, used as an intermediate in the production of other gold compounds and occasionally for colouring ceramics. Gold salts are also used as anti-inflammatory drugs in the treatment of rheumatoid arthritis.
The dissolution or extraction of gold from gold ore is an electrochemical reaction. Gold extraction generally involves two electrochemical reactions [8 ]: (2.7.16) (2.7.17) After the gold is dissolved, it is concentrated by carbon adsorption. Later, it is recovered from solution as metallic gold by electrolysis.
