Copper is extracted from ore by crushing copper bearing ore followed by heap leaching with sulfuric acid and then moving the resulting solution to a tank containing scrap iron and agitating the...
Most copper leaching is done by piling broken ore 0.5 Cu into flat surface, 310m 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 15kg Cum 3.
In an operating cyanide heap leach copper will begin to leach from fresh ore on the heap and if unchecked can build. Heap leaching of copper from the ores of Volkovskoe . Heap leaching of oxidized complex and waste copper ores of the Volkovskoe deposit is considered Based on the results of an investigation the preliminary

Heap Leach TENOVA. Heap leaching is a common extraction technique employed in the processing of metals such as gold, copper, silver and uranium. A typical heap leach operation involves ore excavation from open pit or underground mining, milling of the ore to a particular required size and then heaping the crushed ore on an impervious pad.

The GEOCOAT Process - A heap leaching process that is capable of bioleaching copper concentrates. It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material in a bioxidation heap. The support rock itself may be a low-grade copper ore.
Leaching is bacterially assisted, with air blown into alternate lifts. The total heap and dump leach-liquor yield is 16,500m179h, copper recovery was 58.5 in 2003. Four SX plants, namely Central, Metcalfe, Stargo and Modoc, feed three tankhouses Central, Southside and Stargo.

Solvent extraction amp Electrowinning 03 Outotec has world leading technology for copper recovery from heap leaching operations oxidic copper leaching. Our solvent extraction VSF and modular VSF-X and copper electrowinning technologies are highly robust and can accept variable feed solution composition and yield high quality LME-A grade copper.
Upon reaching the bottom of the heap, the copper laden solution exits and is collected in piping and eventually ponds for pumping to SX. The exiting solution is called pregnant leach solution or PLS. Typically, PLS has 0.52 g l 1 Cu with a pH around 2. Oxide ores typically have leaching times of 90120 days per lift.
