Leaching mixing tank
- Product Introduction: A cyanide leaching mixing equipment designed with reference to American technology.
- Capacity: 6-395 m³
- Applications: The double impeller leaching mixing tank is suitable for gold leaching, adsorption and other mixing operations where the specific gravity is small, the viscosity is low, the settling speed is slow, the ore particle size is -200 mesh accounting for more than 90%, and the slurry concentration is less than 45%.
- Product Improvements: The double-layer impeller ensures uniform mixing and low energy consumption; the impeller is rubber-coated and has a long service life; it adopts multi-point air supply to ensure uniform inflation.
Advantages and Features
- The ore flow moves smoothly, the slurry is mixed evenly, and the power consumption is low
- the air enters the tank through the transmission hollow shaft and is stirred by the blades, and the air is evenly dispersed
- the structure is compact and easy to maintain
- the hollow shaft is ventilated to the bottom, and the air enters the tank through it, dispersed evenly, and has small bubbles
- two new impellers are used, the impeller diameter of the stirring tank is large, the rotation speed is low, and the stirring power consumption is small, which can reduce the wear of carbon
- The stirring intensity is moderate, and the slurry concentration and fineness distribution in the tank are consistent, which can improve the leaching rate of cyanide and the adsorption rate of carbon
- the impeller of the leaching stirring tank is lined with wear-resistant rubber, has low rotation speed and long service life.
Working Principle
The slurry leached out of the mixing tank flows from top to bottom in the center under the drag and stirring action of the double impeller, and diffuses through the peripheral damping plates. Air is fed into the lower end of the shaft, mixed with the slurry and circulates upward to form a uniform suspended mixture.

Case Study
A gold mining plant in Shaanxi built a concentrator with a daily processing capacity of 200t/d in 2010, using a direct cyanide-zinc powder replacement process. Because the originally installed double-impeller mixing tank mixing paddle blades were slightly smaller and the rotation speed was lower, the slurry was unevenly stirred, which was not conducive to the leaching of gold. Later, Huston Mining was contacted to contract the cyanide process. Huston’s modified equipment uses slightly larger stirring blades and is equipped with an anti-backdraft device at the bottom of the hollow shaft. Due to the good ventilation in the center and uniform mixing of sodium cyanide, a major breakthrough was achieved in increasing the gold leaching rate from 94.28% to 97.14%.
