Leaching Agitation Tank

Leaching agitation tank for gold extraction with double impeller, uniform mixing, low energy consumption; the impeller coated by rubber, long service life; multi points to give gas, uniform inflation.

     

 

Smooth movement of ore flow, even pulp mixture, less power consumption; The air enters the tank through the transmission hollow shaft, and the air disperse evenly with the blade agitation; Compact structure, easy to maintain; Hollow shaft is ventilated to the bottom end, and the air enters into the tank with uniform distribution and small bubbles; Adopt two new impellers, the agitation tank is featured with large impeller diameter, low rotation speed, small power consumption, which can reduce the wear of carbon; Moderate agitation intensity, and uniformly distribution in pulp concentration and fineness, which can improve the leaching rate of cyanidation and the adsorption rate of carbon. The impeller of this leaching tank is lined with wear-resistant rubber, low rotation speed and long service life.
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 form uniform suspending mixed liquid. In the gold cyaniding process, leaching agitation tank is applied to leach and carbon-absorb ore pulps whose fineness is -200 meshes and whose density is less than 45%. Under similar circumstance, it is also applied to agitation and leaching in metallurgy, chemical and light industry.
A gold processing plant in Shanxi was built in 2010, the capacity is 200 t/d, and adopted direct cyanide——zinc dust precipitation process. Due to the stirrer paddle of previously installed double impeller agitation tank is a bit small, the speed is low and pulp agitator is uneven, which are against gold leaching. Then Xinhai contracted its cyanide process. Xinhai updated equipment with larger stirring paddle, and added breath prevention device at the bottom of the hollow shaft. Because the excellent ventilation in center and even agitation of sodium cyanide, the gold leaching rate increased from 94.28% to 97.14%.
