Аннотация: The processes of dissolution of elemental sulfur in S-H2O-OH--CN- systems are investigated. These processes simulate the technological processes of cyanidation and the sorption leaching of Au from the biocakes of gold recovery plants in the range of concentrations of the CN- ions of 0-0.02 mol/dm(3) and the range of concentrations Показать полностьюof the OH- ions of 0-0.1 mol/dm(3). Using the simple-lattice planning method of the experiment, mathematical models and "solvent composition-amount of dissolved sulfur" diagrams are constructed for temperatures of 20, 30, and 40A degrees C. It is established that, at t = 20A degrees C, the strongest effect on the solubility of S in the mentioned solvents exerts the concentration of cyanides, while, at t = 30 and 40A degrees C, the larger contribution to an increase in transfer of S into the solution gives the OH- content. The role of hydrolysis that the CN- ion plays in increasing the solubility of sulfur in the studied systems is shown.
