leaching of refractory copper ore

Pretreatment of copper ore prior to heap leaching includes crushing and agglomeration processes which were studied in this thesis research. Crushing is a high energy consuming process. In mining operations generally jaw and gyratory crushers are used for primary crushing and cone crushers are used for secondary crushing. pretreatment of refractory ores prior to gold leaching.Mining and Extraction: Oxide Ores - processes for .Copper is refined from ores in the ground, either through underground or open-pit mines. 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.Copper Heap Leaching & SX-EW Slideshow - MineralsEdHeap leaching & SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution.Copper SX/EW Basic Principles and Detailed Plant DesignNotes: 1. It was based on heap leaching of oxide ore. 2.
