Kinetic Features of Technogenic Raw Material Leaching in Aqueous Sulphuric Acid Solution with Microwave Intensification

Popis výsledku v původním jazyce

In this article, the effect of temperature and microwave irradiation on the apparent activation energy of sulphuric acid leaching of copper slag from Balkhash copper smelter (Kazakhstan) was studied. Leaching was carried out under normal conditions and with microwave irradiation of the raw materials, before and during leaching. Leaching in both cases was carried out at 298, 318 K, 333 K and 358 K. It was found that using microwave irradiation, at 358 K, copper recovery into the productive solution increased from 65.7 % (without irradiation) to 91 %. Apparent activation energy with the use of microwave irradiation decreases from 19.108 kJ/mol (without activation) to 15.517 kJ/mol.
