As the copper is plated the remaining impurities slimes fall to the bottom of the tank these slimes contain the gold and silver the cathodes are removed from the tank and will be around 99959999 copper the slimes are taken to a precious metals refinery where they are refined into finished metal

Blister Copper An Overview Sciencedirect Topics

The produced concentrates are smelted to remove volatile and other impurities and by further purification of the copper melt from the smelter a primary form of the metal known as blister copper is derived higher purity copper is then produced by electrorefining cooper 2005 the main waste materials within this process are the tailings from the flotation stage and the furnace slags from the smelting stage

Copperprocessing

The blister copper then undergoes "fire refining" air and natural gas are blown through the copper to remove any remaining sulfur and oxygen the copper is cast into copper anodes and placed in an electrolytic cell once charged the pure copper collects on the cathode and is removed as 99 pure

Innovations Introduction Tocopper Mining Extraction

The process yields concentrates containing roughly 30 copper which are sequentially fed to a smelter a furnace in which most of the some iron and sulfur are removed then to a converter or converting furnace where most of the remaining iron and other impurities are removed depending on the type of smelting and converting furnace used as much as 99 of the sulfur can be recovered
