WebIn the ESR process, an electrode is prepared by casting or forging after the conventional melting, refining and casting process. The melting of the electrodes occurs in the mould … WebThus, the two factors that most affect the loss of copper to slag in the smelting stage are: matte grade; mass of slag. This means that there is a practical limit on how high the matte grade can be if the loss of copper to slag is to be minimized. Therefore, further stages of processing (converting and fire refining) are required.
