Heap leaching - Wikipedia

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. mo

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.

Major Mines Projects Haib Copper Project

The Haib copper deposit is a rare example of a Precambrian porphyry copper. Porphyry copper deposits are a major world source of copper (also molybdenum, silver and gold) with the best known examples being concentrated around the Pacific rim, in North America, South America, and areas such as the Philippines.

Precious Metal Heap Leach Design and Practice

Precious Metal Heap Leach Design and Practice Daniel W. Kappes1 ABSTRACT Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods.

The mine area has a flat landscape and the water table lies about 25m below the surface, making it ideal for heap leaching. Frontier officially commissioned the solvent extraction (SX) and electrowinning (EW) (SX-EW) plant at the mine in December 2011. Production at the mine is expected to commence in June 2012 and reach 20,000t in 2014/15.

Environmental Risks of Mining

The fluids remaining after the leaching process commonly contain elevated concentrations of metals and radioactive isotopes, posing a significant risk to nearby ground and surface water sources (IAEA, 2005). Additionally, the low pH of ISL mining wastewater can result in acidification of the surrounding environment. Heap Leaching
