Gold CIL production line Process Introduction. CIL (Carbon in Leach) process is the most efficient method to leaching and recovering gold from gold ore, The most protruding features is that leaching and adsorption are carried out at the same time, which greatly saves the cost of construction and operation.

There are 10 main factors affecting gold heap leaching efficiency. 1. Ore Properties. Gold ore with loose structure and large gaps has good permeability, which is beneficial to the penetration and diffusion of cyanide solution inside the ore. The gold in the ore can fully react with the cyanide solution, so the gold leaching speed is faster.

Figure 1 - Gold ore characterization flowsheet (Brooy, 1994) The selection of a flowsheet for free milling ores is relatively simple compared to others. The major factors include comminution circuit selection, heap leaching use, treatment of ores with high silver content, and flotation options for sulfides.
