Abstract

The work is devoted to kinetic analysis and modeling of regularities of formation of metallic gold macroparticles and mechanisms of formation of metal macroparticles. A kinetic model describing the process of formation of metallic gold in the body of technogenic mineral formation is proposed. On the basis of chemical mechanisms of interconversions of different states of gold, including the intermediate formation of colloidal particles, the regularities of the process in water flow are considered. The kinetic model explains the experimental fact of metallic gold accumulation as a result of “chemical evolution” of the system at different depths of artificial mineral formation. Within the framework of the kinetic model, the analysis of the influence on the behavior of the system of concentrations of reducing agents, the intensity of erosion of gold-bearing minerals, the content of “scattered” colloidal gold is given.
