Feb 01, 2009  Agglomeration techniques are widely used by industry to form fine particles into larger masses that are easier to handle and process. One area where agglomeration is potentially useful is in heap leaching operations. Without agglomeration, fine particles travel through the heap, clogging the spaces between the larger particles and resulting in poor leach solution flow.

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.

Heap leaching a stack of gold - Mining Mirror Online

Jul 11, 2018  Agglomeration drums are also called ore drums, agglomerators, and heap leaching drums. Agglomeration is based on a rotary drum design that tumbles ore fines, in the presence of the leachate, through its interior to promote uniformity and to mix the leachate and fines. The agglomeration step happens after the ore is crushed, but before it is heaped.
