JIAPIGOU gold mine production scale of 800t / d, the original beneficiation methods is the amalgamation + flotation, in September 1989 to build the CIP plant, put into operation in January 1991. The total recovery rate of the metallurgical process was 87%. Design indicators: leaching rate of 94.4%, adsorption rate of 99.0%, desorption rate of 99.5%, and volume ratio of 99.5%. Production indicators (June-June 1991) are shown in the table.
