Leaching Copper

Copper Pipes. Copper is one of the materials that easily leaches into low TDS water. The copper will not only leach into the water which copper poisoning is detrimental to human health , but the low TDS water will also cause pitting in the copper pipes that leads to pin-hole leaks.

    How Hydrometallurgy and the SXEW Process Made Copper

    Since the copper ion is exchanged for hydrogen ion, the aqueous phase is returned to its original acidity and recycled to the leaching step of the process. Meanwhile, the copper-bearing organic phase is stripped of its copper by contacting it with a strongly acidified aqueous solution at which time the copper is moved to the aqueous phase while ...

    Benefits of Agglomeration in an SXEW 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.
