Cyanidation Machinery Used in the Gold Leaching -

2019-12-16  The leaching agitation tank is mechanical agitation machine used in cyanide leaching operation of gold mine. The working principle of leaching agitation tank is: with dual impellers rotating and agitating, ore pulps move downward and then diffuse along damping plate. Air is fed in tank from the lower end of shaft, and blended with ore pulps to ...

How does the Cyanide heap leaching process work and

2021-4-2  Cyanide leach mining is a type of gold mining that uses cyanide to extract gold from the surrounding rock. First, the rock that contains gold (the ore) is dug out of the ground, leaving behind a large open pit. Then, the ore is crushed into small pieces. The crushed ore is placed in large piles, called heaps, and sprayed with cyanide solution.
