Gold Ore Processing Plant Leaching Circuit
Comminution Circuits for Gold Ore Processing
However, for suitable ore bodies, a crushing circuit is the default choice for heap leaching (with an agglomeration step often included between crushing and leaching). Crushing plants can also be attractive to consider when expanding existing crushing plants.

Processing Gold by Cyanidation Leaching
Processing Heap Leachable Gold Ore by Cyanidation Oxide ore (low grades) will be unloaded on the heap leach PAD. Lime must be added during the discharge in order to control pH. Harvesting must be performed after the ore discharge is completed in order to avoid compaction caused by the trucks during the leach cell construction.
