Heap Leaching is an ancient process; leaching metals out of ore goes back nearly 500 years. Mines in Hungary recycled copperbearing solutions through waste heaps in the 1550s, Spanish miners percolated acid solutions through large heaps of oxide copper ore on the banks of the Rio Tinto in 1752 and one of the classical methods for the manufacture of copperas (iron sulphate) was to heap up iron ...
Leaching. Most copper leaching is done by piling broken ore (∼% Cu) into flatsurface, 3–10m high, 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3.
Carbonate concentrates are a relatively minor product produced from copper cementation plants, typically as the endstage of a heapleach operation. Such carbonate concentrates can be treated by a solvent extraction and electrowinning (SXEW) plant or smelted.

About 80% of the world''s copperfromore is produced by concentration/smelting/ refining of sulfide ores. The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores. Copper production from recycled endofuse objects is about 15% of copperfromore copper production.

The Lady Annie Copper Project, located 137 km north of Mount Isa, is a large medium grade oxide copper resource. The project is a Mt/y copper heap leaching operation comprising crushing, agglomeration, stacking, heap leaching, solvent extraction and electro winning (SXEW) to produce 19 000 t/y of LME A Grade copper cathode.
The "ball and chain" provided a simple guide to stacking height such that once the copper ore reached the ball the plant operator would move the stacker slightly to the side and continue stacking. Consistent stacking of the ore height improves the copper ore heap leaching process in several ways.
Improvements in Copper heap leaching by use of wetting agents Proceedings of EMC 2009 3 A sprinkler system is installed on top of each heap allowing the diluted sulfuric acid to be fed uniformly over the ore. While the solution percolates through the heap, copper is leached out of the ore.
Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two decades of this century, whenopen pit mining, flo tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leachingsolvent extractionelectrowinning, the basic methods ...
The ndida Mine is located in the Atacama Desert, Chile. In 2012 it accounted for five per cent of global copper production and around 15 per cent of Chilean copper production. The mining operation includes an oxide ore heap leach plant processing approximately 20 mt/y of ore.
The El Abra operation consists of an openpit copper mine and a SX/EW facility with a capacity of 500 million pounds of copper cathode per year from a 125,000 metric tonperday crushed leach circuit and a similarsized ROM leaching operation.
Alena opens describing the heap leaching process for copper: Copper ore is excavated from the ground, crushed and then spread in uniform layers on a pad. A slow trickle of sulfuric acid is distributed over the pile, where it percolates to the bottom and a collection point.

There are two main leaching methods: heap leaching and insitu leaching. Heap leaching is the most common method used in the When processing copper through heap leaching, vast quantities of ore and overburden overburdenSoil and rocks that have been moved out of the way to get to ore are called "overburden." In areas where there are high ...
The PLS is captured in production wells and pumped to a leach plant where the copper is later recovered. High levels of TENORM have been found in the PLS of two insitu leach operations in Arizona. Dump Leaching. Dump leaching refers to leaching that takes place on an unlined surface.
