design setups for gold tank leaching

The process design of gold leaching and carbon-in-pulp

The gold aurocyanide complex in the aqueous phase is readily adsorbed onto the activated carbon. By the time the pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-

Leach Circuit Design Principles | SRK Consulting

The tank material of construction (e.g., carbon steel, stainless steel, other metal alloy or non-metallic) is a function of the chemical and physical interaction between the ore and the process equipment. Agitator design is determined by whether the aim of the agitator is to simply keep the material suspended or the need for efficient introduction of air/oxygen for the leach reaction.

CIL gold processing plant - CIL processing plant

Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98%. It has become the first choice of modern gold mining and beneficiation plant design. Application: CIL mainly applies for

Cyanide Leaching Of Gold - Mine Engineer.Com

Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30%, which is not a worthwhile venture. The use of alkalies such as calcium oxide, will prevent the decomposition of cyanide in solution to form hydrogen cyanide gas. It reduces the volume of cyanide required to leach the gold or silver. In

In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in

Tank leaching - Wikipedia

Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: 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;

Improving the process performance of gold cyanide leaching

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- pumping hydrofoil impellers, which requires a low mixing power input and results in low shear rates inside the reactor.
