Vat Leaching of Finely Crushed Gold Ore

2021-2-26  Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak ...

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.

Copper Dump Leaching and Management Practices

Vat Leaching Vat leaching is used to extract copper from predominantly oxide ores by subjecting the ore to concentrated sulfuric acid in a series of large tanks or vats. Vat leaching has been preferred to heap leaching in cases where high-grade ore requires crushing to permit adequate contact between the leach solution and the copper minerals.
