摘要：

Metal recovery from "Waelz oxide," the product obtained from steel foundry dusts through a pyrometallurgical process, and the slag obtained in this process has been carried out by liquid-liquid extraction. For this purpose, leaching of the solid samples was attained by microwave digestion with HCl. The extraction of 13 elements in the leachates was studied using the alkylthiophosphinic acid Cyanex 302 in kerosene and varying the acidity conditions and the extractant concentration. The experimental results on the extraction of cadmium, lead, and zinc have been compared with the theoretical behavior obtained by taking into account equilibrium extraction data reported for the extraction of these elements from synthetic individual solutions.
