摘要：
The aim is to identify the kinetic characteristics of the leaching of copper-ore deposits Priorsky sulfuric acid solution. To identify the kinetics of the leaching process used a graphical method of van't Hoff and Arrhenius uravnenie. As a result of established that the process of leaching copper-bearing ores, the activation energy which was 11,08 kJ/mol, flows in the mixed region with a predominance of diffusion factors. Recommended leach copper from the ore deposit Priorsky with vigorous stirring, grinding the starting material, the concentration of sulfuric acid is not less than 0,5 mol/l and a temperature of 60 degrees C. The field of application of the results is the hydrometallurgical processing of copper-bearing ores and materials.
