The experimental study is aimed to identify the patterns of Au sorption/deposition by various natural substances in an acidic conditions (pH=2). The experiments simulate the conditions of the dispersion train of the Ursk tailings (Kemerovo region, Russia), where active concentration of Au by natural organic matter in an acidic conditions is observed. It was found that the degree of extraction of gold from a sulfate solution is generally higher than from chloride solution. This may indicate a greater kinetic inertness of Au chloride complexes in an acidic medium than sulfate ones. When sulfate ions predominate in the solution, more active deposition of gold is observed. According to the degree of deposition of Au, a series was established (from larger to smaller): a mixture of clay minerals (smectite + palygorskite + muscovite)> humic acids> kaolinite.
