Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

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.

minus 20 mm. The ore passes to agglomeration and then is sent to heap leaching. Sulphuric acid is added to keep the pH optimum. The pregnant solution from heap leaching is subjected first to copper SX and EW to recover the copper and second to zinc SX and EW to recover the zinc after removal of some impurities such as iron, silica, etc. The

Copper SX-EW Bleed - emewCorporation

Heap leaching is used around the world to recover copper from low-grade oxide deposits. As with any hydrometallurgical process, there is an intrinsic need to bleed a portion of electrolyte for impurity control. In the case of SX-EW operations, this bleed often deports to the raffinate pond which negatively affects the leach efficiency in the heap.

A Simplified Economic Filter for Open-Pit Mining and Heap .

leaching of copper from run-of-mine or crushed ore placed on dumps, followed by extraction of highly-pure copper from the leach solutions by solution extraction and electrowinning (SX-EW), is increasingly used due to its relatively low costs. Not all ores are amenable to leaching, hence many mines employ both methods. A few mines extract
