Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different.

  • What are tailings Their nature and production

    Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990).

  • Development of a Combined Flotation and High Pressure

    The present study focused on the re-processing of copper and nickel from mine tailings. In this work, recovery of copper and nickel from mine tailing by combined process of flotation and high pressure oxidative leaching were considered. In the first stage, effects of flotation parameters including collector type, collector dosage, and pH and pulp density were examined.

  • Copper extraction Wikipedia

    Copper extraction refers to the if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings. When rich enough, native copper ore bodies may be treated to recover the contained copper usually in a heap leaching or dump leaching process to liberate the copper minerals into a solution.

  • Benefits of Agglomeration in an SXEW Process for Copper

    This will likely further increase the importance of the SX-EW process in future copper production. In addition to ore deposits, SX-EW has become a viable means of processing tailing piles, which were previously considered a waste because the ore in them was either too low grade to be worth processing, or because it had since oxidized.

During the alkaline leaching process, the pH of PLS decreased remarkably with an increase in the leaching time, as shown in Fig. 3(a). In the initial 10 days, pH differences were small as a result of less bacterial activity.
