Applied Field: Carbon in leach plant is mainly suitable for processing gold oxide ore with low associated silver, which can save the investment cost and obtains higher and more significant economic benefits than traditional methods such as zinc powder replacement.
Classification ofCarbon in Leach Plant
The cyanidation gold extraction process is the main method of modern gold extraction from ore or concentrate. It includes several basic processes such as cyanidation leaching, washing and filtering of leaching pulp, extraction of gold in cyanidation liquid or cyanidation pulp, and smelting of finished products.The existing cyanidation plant basically uses two types of gold extraction process. One is the conventional cyanidation process that uses thickeners to perform continuous countercurrent washing and replaces precipitation with zinc powder to recover gold. The other is a non-filtering cyanide carbon slurry process, which uses activated carbon to directly absorb and recover gold from cyanide pulp without filtering and washing. According to the different materials, the conventional cyanidation process can be divided into two types: one is the small carbon in leach plant which deals with the flotation gold concentrate, or the mercury mixing and gravity separation tailings. The other is a gold extraction plant that processes argillaceous oxidized ore and adopts all slime stirring cyanidation.
Process Advantages of Carbon In Leach Plant
1.Carbon in the leach plantcan effectively reduce the carbon abrasion of the slurry on the continuous pumping and vibrating screen surface, reduce the cost, and facilitate the maintenance and operation.
2.99% of gold can be resolved in 2-6 hours by using the high temperature and high-pressure desorption method.
The concentration of gold and silver cyanide complex ions in the precious liquid is relatively high, while the impurity ions are less. The high purity solid gold can be obtained safely and economically by the integrated high efficiency and low consumption rapid analytical electrolysis system.
