leach tanks. Cyanide is a lixiviant, which is used to leach gold from solid matrixes to form a gold-cyanide complex. The concentration and dose of cyanide used are very low in comparison to the live liquid volume in the tank. The pH of the resulting slurry would be carefully controlled by adding lime or another alkali ensuring that
Sodium cyanide is added to leach the gold and silver. The bulk of the sodium cyanide is added to the first and third tanks. Activated carbon is present in all but the first tank to adsorb the dissolved gold and silver. The slurry in each tank flows through submerged E.P.A.C. screens and moves by gravity to the next tank in the series.
At a slurry concentration of 50 solids, the slurry passes. through a series of agitated mixing tanks with a residence time of 24 hours. The gold bearing liquid is then separated from the leached solids in thickener. tanks or vacuum filters, and the tailings are washed to remove gold and cyanide

Jul 13, 2016 For gold ores agitation periods vary from 16 to 48 hr., probably averaging 30 hr., and for silver ores nearly twice this period. Dilution during agitation varies from 1 of solution to 1 of solids by weight to 3 of solution to 1 of solids, occasionally higher, probably averaging 2 to 1. Operation is continuous through a series of agitators ...
After mixing, the slurry flowed into the double-impeller agitation tank, and the cyanide removal process continues. After reaching the standard, the slurry was pumped into the chamber filter press through the slurry pump for de watering, and the tailings were loaded and transported. The filtrate enters the buffer tank for buffering, and then be pumped back to the first high-efficiency ...
Introduction Gold CIL process carbon in leach is an efficient method of extracting and recovering gold from its ore.By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to 99, which is the first choice of modern gold mining and gold beneficiation plant.

Generally, leach tank agitators are designed to keep the pulp in motion, i.e. 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 . In an effort to improve mixing the air flow is typically increased.

The 2 meter diam. x 2.5 meter high covered and ventilated mix tank is equipped with a 3 HP agitator. The mix tank is fitted with a one ton cyanide bag breaking hopper or a 1350 kg cyanide flow bin and a pressure gauge to indicate solution level.
Oct 06, 2020 A cyanide leaching circuit usually consists of large agitated tanks for mixing mineral slurry with cyanide in order to extract gold. Typically, the slurry consists of 30-40 solids by weight with the solid particles being less than 100 microns 0.1mm in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction.
