  • Silver Refining and Recovery

    Silver Refining and Recovery

    Copper sulfide concentrates are smelted, resulting in blister copper, which contains approximately 9799% of the silver that was in the original concentrate. The blister copper is then electrolytically refined and 'slimes' accumulate on the anode or at the bottom of the refining tank. These slimes contain insoluble impurities, like silver.
