Soaking (Leaching) includes two major methods:

Heap Leaching (HPL)
The ore that was destroyed was stacked on a secure layer, and then it was built on a shelf. Dipt The solution is a sizzling solution, a solution that cuts through the pile, dissolves the gold, and ▪ a rich soluble is collected at the base for extraction.

System Tong / Tank Leating (CIL/CIP)
Ore is put in tank Procession, mixed with cyanide solution, and stirred. or CIP (Carbon-In-Pulp) adds active charcoal to redistribution Gold directly inside the tank, separating it from the solution.

Both effective methods for fine ore or low levels, but heap leaping more economical for large volumes with low levels, while Tank leaching give control process and recovery higher for medium-to-high ore.
