  • Recovery of Gold and Silver from Copper Anode Slime

    Recovery of Gold and Silver from Copper Anode Slime. To extract the gold with thiourea, it is necessary to first remove the copper, selenium, tellurium, and most of the silver from the mixture. Once these elements are removed, the gold and most of the remaining silver can be extracted in high yields by leaching with thiourea solutions.
