Cyanide Leaching Tank - colorholland.nl
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. 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. CIL is slightly different from ...

Tank leaching - Wikipedia
Tank leaching is usually differentiated from vat leaching on the following factors: 1. In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

Gold Agitation Cyanidation Leaching
The agitation leaching method is to concentrate the slurry, obtained after grinding and classifying of the gold-containing ore, to a suitable concentration, place it in a leaching tank, add a cyanide solution, and aerate to carry out leaching.
Improving the process performance of gold cyanide leaching ...
dissolve, gold cyanide leaching reactors are usually very large, with a size of up to 5000 m3. For the same reasons, the solids content in tank leaching is kept at a high level, around 40 wt.%. Currently, a typical agitator configuration in a cyanide leaching reactor is two downward-pumping hydrofoil impellers, as illustrated in Figure 1.
Application Note Cyanide Leach Process - pH
The leaching process will take from 60-90 days. High grade ore is typically reserved for agitated leaching. fi nely ground ore (< 200 mesh) is combined with the cyanide solution in a series of tanks. This slurry is referred to as “pulp”. Agitators and air / oxygen are added at each tank. The oxygen reacts with the sodium cyanide to
The process design of gold leaching and carbon-in-pulp ...
Leaching 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 9.5–11 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 ...
