Abstract A response surface method using aposite design was employed to evaluate, model and optimize the influence of five main factors in the gold cyanidation process. These factors were pH, solid percentage, NaCN concentration, particle size and leaching time.
An important factor inminution and sizing operations is the determination of the particle size distribution of the materials being processed, commonly referred to as particle size analysis. Many techniques for analyzing particle size are used, and the techniques include both off line analyses which require that a sample of the material be taken for analysis and on line techniques that
Cyanide leaching process is one ofmon gold ore beneficiation processes. The process index depends on factors such as gold particle size, sulfide content, ore block size, leaching speed, leaching time, cyanide concentration and leaching slag washing degree.
A cyanide leaching process can be conducted under different technical conditions. An effective technique for well leachable high grade gold ores is agitation leaching. Thereby an ore pulp with grain sizes of < 100 microns is permanently agitated during its leaching in special tanks e.g. Pachuca tanks. The leaching period is generally less than 24 hours. The gold recovery lies usually above
Factors influencing leachingics The equations arrived at 14 and 22 for reaction controlled and diffusion controlled leaching, respectively, have implications on the operating cost for leaching operations. Such costs are for example size reduction by grinding, leaching temperature and
