Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

0.3% Cu for copper oxide ore) or strong leach solution (pH of copper sulfide ore leach solution is 1.1 and pH of copper sulfide ore leach solution is 2). Column leaching results also show that about 80 to 90% of copper was recovered from the copper sulfide ore in a very short leaching time irrespective of crushing technique.

Heap Leaching an overview ScienceDirect Topics

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 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.

The heap leaching of copper bearing ores is improved by using sodium nitrate as an oxidizing chemical reactive in a sulphuric acid leaching solution. In particular, the ore is crushed to <6 mm and stored in heaps less than twelve meters high. The heaps are irrigated with a dilute solution consisting essentially of sulphuric acid and sodium nitrate to produce a leach product.
