  • Publication number: 20200172993
    Abstract: A method and a system for gold and silver recovery from a pregnant solution resulting from gold extraction from an ore using halogen, the method comprising lowering the oxidation reduction potential of the pregnant solution by mixing the pregnant solution with a reducer over the surface of a bed of silica, and flowing the mixture through the bed of silica. The system comprises a bed of silica, a feeder controlling feeding of the pregnant solution with a reducer to direct a mixture of an ORP less than 550 mV to the surface of the bed of silica, and a collector receiving a barren solution from the bed of silica after flowing of the mixture therethrough.
