Abstract: The present application discloses a gold recovery system and recovery method thereof from a gold separation solution, where the recovery system includes an gold selective extraction system, a reduction system, a washing system, and an evaporation system; and the recovery method specifically includes the following steps: (1) primary extraction; (2) secondary extraction; (3) gold precipitation by reduction; (4) washing of gold powder; and (5) evaporation of waste solution. In the present application, by using chloride ions to recognize AuCl4?, the gold-rich solution is directly reduced to produce qualified gold powder product (99.995%); the gold-barren solution and the post-reduction solution are evaporated and concentrated, with the condensate reused to realize the recovery and regeneration of chloride ions, the recycling of the extractant and no generation of waste solution or waste gas in the production process.
