Copper Heap Leaching | Encyclopedia MDPI
A typical heap leaching circuit is shown in Figure 1. This process is conducted in leaching piles, where their typical height is between 4 and 10 m, although in some cases, they can reach 18 m [ 28]. In addition, the largest sizes generally range between 10 and 40 mm in heap leaching, and sizes less than 6 mm are unacceptable.
