Copper Refining Process Steps

Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent .

  • Liberating Copper and Nickel A True Story

    Liberating Copper and Nickel A True Story

    Unfortunately the copper refining process doesnt end there and it is here where this story gets interesting. As the impure copper from the anodes dissolves into solution and is replated onto the cathode as pure copper the dissolution process is faster than the plating process causing a gradual build up of copper ions in the refinery electrolyte.

    • Figure 6.3.2. Typical flow sheet for a copper refinery. The process for electrorefining copper is typical of those carried out in aqueous solution. The electrolyte is copper sulfate 0.7 molar and sulfuric acid 2 molar and the way in which the purification of the copper occurs can be seen by considering the

  • Copper Refining an overview ScienceDirect Topics

    Copper Refining an overview ScienceDirect Topics

    In the electrolytic process copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth adherent one. In this feature it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.

  • What Is Copper Smelting with pictures

    What Is Copper Smelting with pictures

    Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

    The slag produced in the chlorine-refining step of my process contains sufficient copper values to make it economically feasible and desirable to treat the slag specially to recover such values. After the chlorine-refining step is completed the molten slag is tapped into cooling pits and allowed to cool until the slag solidifies.
