• 01

  Three stage and one closed-circuit crushing and screening--heap leaching--carbon adsorption--gold extraction process
  

• 02

  Crushing and screening stage: According to the raw ore processing capacity , the maximum size of the raw ore, the final product crushing size and the nature of the ore and other factors, the three-stage and one closed-circuit process was adopted, that was coarse crushing+medium crushing+fine crushing+preliminary screening and checking screening.

  Heap leaching process: it adopted multi-layer method of pile building and spray leaching process, the pregnant solution of heap leaching flowed to the pregnant solution pool, and the intermediate liquid of heap leaching returned to the mine pile for cyclic spraying.
  

• 04

  Carbon adsorption and gold extraction process: the pregnant solution was extracted using the carbon adsorption, desorption electrolysis and smelting gold extraction process. The carbon adsorption lean solution returned to the heap leaching yard for cyclic spraying, the desorption lean solution returned to the carbon adsorption operation, and the electrowinning lean solution returned to the desorption operation. In the end, we smelted to get the final product-crude gold.
