【 Capacity 】: 6-395m3
【Improvement】: 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
1、Entering leaching tank via hollow shaft, air is agitated and dispersed by rotation of impellers.
2、The two new type impellers with large diameter, low speed and low power consumption, which can reduce the wear of carbon.
3、The moderate stirring intensity, pulp concentration and fineness distributes consistently can improve the adsorption rate and import rate.
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%.
