All Slime Cyanidation Carbon-in-leaching Gold Extraction and Smelting Technology (CIL Plant) is a gold-extraction technique in which several major processes are involved. The gold ore is first ground to ore pulp (particles of -200 mesh takes up over 90-95% of the total) which will go through cyanide leaching, and then the soluble gold-bearing minerals in the pulp are directly adsorbed by the activated carbon. Finally, by carbon desorption and electrical winning gold mud is produced. Seven sessions constitute this technique: raw materials preparation, agitation and cyanidation leaching, countercurrent absorption with activated carbon, desorption and electrical winning of gold-bearing carbon, melting and casting following separation and purification of gold mud, reactivation of active carbon and disposal of cyanide-polluted sewage

This technology features mature technical skills, high recovery ratio and the final goods are gold bullions.

Double-impeller leaching tank is a equipment used for gold cyanidation leaching process and absorption, two transmission ways, one is the planet-cycloid reducer drive; the other is the plane envelope reducer drive.

This equipment working conditions: pulp concentration ≤ 45%, pulp concentration ≤ 1.4 t / m

Double impeller leaching tank equipped with motor, cycloidal planetary gear speed reducer, bearing block and agitating shaft, is characterized by compact structure, little occupied space, and the agitating shaft equipped with a double impeller , from the top view the impeller rotating clockwise, each impeller composed of 4 blades, and the angle of the top blade and the below one is 45 degree. The compact air gets through the elbow pipe or the hollow shaft to the tank’s bottom, the raising air plays the role of mixing , at the same time the big bubble shattered by the impeller changing into small bubbles, in the end the pulp and air reaches fully mixing and sodium cyanide solution contacts with the pulp completely, thereby gets the better gold leaching result. The design of this device keeps the impeller low-speed moving, reducing the possibility of wearing or smashing the active carbon, so as to achieve high leaching rate, high absorption rate and collects more gold.

Agitator impeller driven by the motor, and pulp flow to tank’s bottom, in order to prevent bottom’s wear, base plate lined at the bottom to extend the service life
