Gold Extraction - an overview ScienceDirect Topics
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.

2022.10.15 The use of halides as gold lixiviants occurs earlier than cyanide (La Brooy et al., 1994). Chlorination was extensively used in gold extraction in the late 19th century until the development of cyanidation, a more economical process with a higher stability complex, rapidly replacing chlorination.
