  • Benefits of Agglomeration in an SX-EW Process for Copper

    Heap Leaching Copper Ore with Agglomeration. Crushed copper ore is first typically processed via heap leaching. An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered. For this reason, the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator.

  • Effect of ore size and heap porosity on capillary process

    Recovery of the target metal can range from approximately 30% for some difficult to leach sulfide copper ores to over 90% for easier oxide gold ores [5].
