    The electrolytic refining of copper produces the high quality, high purity copper required by industry. Even the best chemical method cannot remove all the impurities from the copper, but with electrolytic refining it is possible to produce 99.99% pure copper. Copper cathodes are hung between anodes.

  • Innovations: Introduction to Copper: Mining & Extraction

    Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.

    Dissolved copper from the anode is electrolytically deposited on the stainless steel cathode plate. After about 10 days of electrolysis, the cathode is lifted out and stripped from the stainless steel plate, resulting in the completion of refined copper (with grade of 99.99%) as a final product.

    The resulting copper mixture is called concentrate, which is a grey-black powder that looks a bit like ash. It is roughly 30% copper, and may also contain traces of gold and silver. The copper concentrate then goes to a smelter, where it undergoes several chemical processes at high heat in order to remove iron and sulfur. (The resulting sulphur dioxide emissions are captured and recycled into sulphuric acid,
