Product description
The adsorption column is a device that adsorbs gold from heap leach noble liquid with activated carbon as the medium. Activated carbon is a porous material with special adsorption properties. Gold mixed with chloride or cyanide is strongly adsorbed by activated carbon. Granular activated carbon is packed in an adsorption column. When the purified solution passes through the activated carbon, the purpose of adsorbing gold therefrom is achieved. The use of granular activated carbon to recover gold from a solution includes the following steps: carbon adsorption, carbon elution or desorption, carbon regeneration, and gold recovery from the desorption liquid by electrodeposition or displacement precipitation.
 
Working principle
Recovering gold from the heap leach noble solution, although the zinc replacement method or the ion exchange resin adsorption method can also be used, the activated carbon adsorption method is still simpler and more effective for larger heap leaching. The activated carbon adsorption of gold in expensive liquid usually uses multiple adsorption columns (or tanks) in series. When a certain volume of noble liquid is passed, the first adsorption column is saturated with gold, the second carbon adsorption column is changed to the first adsorption column, and the original first adsorption column is replaced with new carbon. Columns, and so on.
