  • How can you increase the copper recovery of your SX-EW

    Decreasing the recirculating copper load allows for an increased recovery of copper in the leach and increased capacity of the SX-EW plant. Increasing recovery of copper by 5-10% will improve the profitability and decrease the working capital of the plant, with minimal capital outlay. By not removing the recirculating copper load, the overall

  • TENORM Copper Mining and Production Wastes Radiation

    Sep 14, 2016 · During in-situ leaching, rather than removing soil and rock to reach copper deposits, acids are injected into ore bodies via wells.
