the cyanide leaching of sperrylite, possibly due to its low solubility in solution. Ferricyanide has been investigated as an alternative oxidant to oxygen in the cyanide leaching of certain gold and silver sulphides which are similarly slowleaching in cyanide (Xie and Dreisinger, 2009; Xie et al., 2008).

Technical Report Treatment Of Cyanide Heap Leach And Tailings

+

In the CIP method, a slurry consisting of ore, water, cyanide, and lime is pumped to the first series of tanks for agitation and leaching. Gold is leached from the ore in the leach tank train. The slurry containing leached ore and pregnant solution is pumped to the second series of tanks for gold recovery.

pH / ORP measurement Cyanide leaching process

+

The control of pH in a cyanide leach solution is critical from both safety and cost perspectives. The process adds cyanide to a solution in the form of sodium cyanide (NaCN). Decreased pH values favor the following reaction: NaCN + H2O–>HCN + NaOH The result is the formation of hydrogen cyanide gas that is lethal in a concentrated state.

Cyanide will preferentially leach sulfide minerals and will react with sulfur to produce thiocyanate. These reactions will also enhance the oxidation of reduced sulfur species, increasing the requirement for lime addition to control the pH at a sufficient level to avoid the volatilization of hydrogen cyanide (HCN).

cyanide solution1−3. By reaction with oxygen and cyanide ions, silver is converted into a stable cyanide complex ion which is recovered from the leaching solution by di erent methods. However, the high toxicity of cyanide results in severe environmental consequences 4. Therefore, cyanide causing irreversible destruction of nature should not be used in any quantities.

Gold ore cyanide leaching process includes several approaches, heap cyanide leaching, CCD (countercurrent decantation), CIP (carbon in pulp), RIP (resin in pulp) and CIL (Carbon in leaching). Heap cyanide leaching is applied for low grade (grading 3%) gold ore, ore powder, beneficiation tailing and leaching residue.
