inside the carbon in pulp (CIP) tanks. The coarse laden carbon particles are screened out of the last tank, washed with caustic to remove the gold cyanide, and the gold metal is produced using a process called electrowinning. Due to the rapid reactions taking place in an agitated leach process, automatic pH control is strongly recommended.
Gold Leaching( carbon in leach) process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with highgrade silver.
Agitated Tank Bioleaching Bioleaching processes in mechanicallyagitated tanks are usually applied for the treatment of flotation concentrates derived from sulfidic ores. The valuable components in these concentrates can be gold, uranium and a variety of base metals such as copper, nickel, zinc and cobalt.
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 carbonabsorb ore pulps whose fineness is 200 meshes and whose density is less than 45%.

· The optimum sparging system depends on the geometry of the leach tanks. For example, conicalbottomed Pachuca tanks with single sparging points (common South African practice prior to about 1980) and flatbottomed leach tanks with multiple sparging points, or simple downtheagitatorshaft addition, have all been used.

· the rst leach tank fi at a rate of 160 m 3/h. There are seven leach tanks in series; each tank is m in diameter and 12 m in height, with a working capacity of 1100 m 3. The tanks are constructed from mild steel and each tank is agitated by a double stage 4blade propeller, diameter m, driven by a 55KW electric motor. The residence ...
The performance of an industrial tank agitator can be directly affected by the critical speed of the shaft and impeller assembly. Operating an agitator at a rotational speed that is close to or at the critical speed for the shaft assembly can result in significant shaking. This article provides a detailed overview of critical speed including ...
· The ores are then placed in an agitated tank for leaching of copper oxides with weak sulphuric acid. Testing has indied 84% recovery of total copper with leach times of 16 to 18 hours; however, the addition of waste heat from the sulphuric acid plant could further reduce the leach times.
dissolved oxygen levels in leach circuits. one key advantage SlamJets offer is their ability to produce microfine bubbles. Traditional sparging systems rely largely on agitator shear to reduce bubble size. This method is inefficient and not capable of producing fine bubbles, resulting in much of the oxygen escaping from the tank
The Albion Leach Reactor consists of the following components: A corrosion resistant alloy steel reactor that utilizes Glencore Technology's revolutionary ZipaTank™ modular tank technology. Glencore Technology's fully modular tank shell, base and roof systems can be rapidly installed on site in one third the time of a field welded tank and at ...
The leach may require 24 to 72 hours to complete, and after the leach is completed, the leached slurry is routed to the CIP circuit. In CIP, adsorption of gold and silver onto activated carbon is completed in agitated tanks with interstage screens used to retain the activated carbon within the tank.
