FEATURES OF INTERCRYSTALLINE AND INTERPHASE DIFFUSION PROCESSES IN ACTIVATION HEAP LEACHING OF DISPERSED GOLD

The authors have developed a model of the activation of cyanide leaching of gold based on known experimentally established fact of the effective dissolution of gold in a narrow range of pH=9.3-10.7. According to the results of the pilot tests were analyzed kinetic param-eters of percolation leaching of Au for the standard and experimental (photoelectrochemical) schemes. Identified some features of standard models and experimental schemes of leaching after the analysis of the distribution of points describing the value of the gold content.


Keywords

Gold leaching, clustering, dispersed forms of gold, diffusion processes.
