Doubleimpeller agitation leaching tank is an equipment used for gold cyanidation leaching process and absorption. It has two transmission ways, one is the planetcycloid reducer drive; the other is the plane envelope reducer drive. working conditions: pulp concentration ≤ 45%, pulp concentration ≤ t .
22 rows· In the gold cyaniding process, leaching agitation tank is applied to leach and carbon .
Ineffective Agitation – Reduction of solids in suspension . Generally, leach tank agitators are designed to keep the pulp in motion, down the centre, out to the wall an up the tank sides. In some leach tanks air blowers introduce air flow below the agitator blades which can cause an erratic slurry flow and inefficient mixing .
takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around –11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in
Extraction of gold by using a tank leaching systems typically use a lot of multiple tanks in series within a building. Different from heap leaching are located at the open air. Gold leaching process carried out by stirring the gold ore is mixed with limestone and added with a solution of cyanide in a tank .
The agitation leaching method is to concentrate the slurry, obtained after grinding and classifying of the goldcontaining ore, to a suitable concentration, place it in a leaching tank, add a cyanide solution, and aerate to carry out leaching. The main equipment used in the agitation leaching process is a cyanide leaching tank.

The development of fundamental laws governing the operation is complicated by the large number of variables involved, some of which can hardly be evaluated in mathematical terms.
(2) 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%. Under similar circumstance, it is also applied to agitation and leaching in metallurgy, chemical and light industry.
On the CIL processing of free milling oxide gold ore, how far I can drop the free cyanide concentration in the leach tank#1? In order to minimize the cyanide consumption without any impact on gold recovery! Currently our practice in the 1st leach tank the cyanide concentration is 165 ppm and there i

In tank leaching the ground, classified solids are already mixed with water to form a slurry or pulp, and this is pumped into the tanks. Leaching reagents are added to the tanks to achieve the leaching reaction. In a continuous system the slurry will then either overflow from one tank to the next, or be pumped to the next tank.
Improving the process performance of gold cyanide leaching reactors M. LatvaKokko, T. Hirsi, T. Ritasalo, and J. Tiihonen ??? Cyanide leaching of gold is carried out in very large mechanically stirred tank reactors. The reactor size can be up to 5000 m3. A typical agitator configuration is two downward
Double impeller leaching agitation tank for gold extraction of carbon in leach Leaching tank used in Yunnan Jinshan CIL plant with 400tpd Doubleimpeller leaching tank is a equipment used for gold cyanidation leaching process and absorption, two transmission ways, one is the planetcycloid reducer drive; the other is the plane envelope reducer drive.
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents ...
Agitation leachingPractice Cyanide and the Gold Industry Introduction. One of the most widely used industrial practices is the cyanidation process in the gold industry. Amount of gold present in ores typically occurs at very low concentrations in ores which generally range from less than 10 gm/tonne.
Product Application of Double Impeller gold leaching tank with agitator Gold ore leaching tank features of reasonable and compact structure, high transmission efficiency. Gold ore leaching tank is widely used in gold and silver ore dressing plant for cyaniding treatment, CIP process, and carboninleach .
Agitation Leaching Tank is mainly used in cyanide leaching of gold producing and sewage treatment of cyanide factories. It is also used in metallurgy, chemical industry, and light industry. In carbon slurry process and cyanide process, the leaching tank should be used together with carbon screen, carbon pulp, and other auxiliary equipment.
Stirred tank bioleaching is mainly applied on refractory gold concentrates with gold concentrations in the range 10150 g/tonne. In a refractory gold concentrate very fine gold particles are locked into the sulfide matrix and to liberate the gold for subsequent recovery by cyanide leaching .
Gold ore leaching tank adopts two new type bigger impellers, low rotational speed,less power consumption, inside hollow shaft can suck the air into the tank,and improve the leaching environment. Gold ore leaching tank is widely used in gold and silver ore dressing plant for cyaniding treatment, CIP process, and carboninleach work.
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.
Apr 15, 2014· My home made leaching tank was made March 2014 for handling small quantity of Gold Stone,working together with some technique like Carbon System_Electrolysis System,many gold .
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%.
Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while impurity remain can then be washed out and processed to give the pure metal; the material left over is commonly referred to as to pyrometallurgy leaching is easier to perform, requires less energy and is ...
Aug 03, 2016· Applications of this series agitation tank are different from the conventional agitation equipment, which are used for agitating, leaching and carbon absorption in the gold cyanidation plant with ...
