Heap Leaching - an overview ScienceDirect Topics. In heap leaching, the mined ore is crushed to size, usually below 20–25 mm, and heaps are scientifically prepared and engineered on prepared bottom pads. In vat leaching, more finely crushed ore 1–10 mm is placed in a large basin vat flooded with leachant solution and left to react with time ...

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.

This has allowed heap leaching to be extended to treat secondary copper sulphides, where lower acid strengths are typically employed and sufficient air permeability becomes a requirement. The application of bacterial heap leaching to refractory chalcopyrite ores introduces further complexity, such as the need to improve leach kinetics by raising the heap temperature. High leach temperatures (>50°C)

Heap leaching a stack of gold - MiningFeeds

25/04/2018· Since then, heap leaching has been adopted successfully by many mines across the world. Heap leaching occurs after the mining and crushing of low-grade ores, usually in an opencast mine. High-grade ores and ores not amenable to cyanide leaching at coarse particle sizes require further processing to recover the gold values. These processing methods can include further grinding, concentration, …
