Leaching Process Copper Ore

Copper recovery using leach/solvent extraction .

The first process, vat leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of high-grade oxide ores was decreasing and vat leaching was on the decline. The second process, heap and dump leaching of low-

Bioleaching - Wikipedia

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.

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.
