“…One study [16] revealed significant challenges in the extraction of precious metals from zinc production clinker, suggesting effective treatment methods for this technogenic material. Another study [17] compared pyrometallurgical and hydrometallurgical methods for processing clinker, highlighting the latter as more promising and efficient. These studies emphasize the importance of an integrated approach, including magnetic separation and electro-leaching, which contributes to cost reduction and increased environmental efficiency, entirely relevant in the context of the present research.…”

This article presents a cutting-edge approach to microwave-assisted processing aimed at enhancing the efficiency of zinc extraction from materials characterized by a high degree of processing complexity. The described technique encompasses two sequential phases: phase transformation under microwave irradiation and leaching in sulfuric acid at ambient temperature. During the phase transformation, implemented through the application of microwave energy, insoluble zinc phases undergo a controlled transition. The experimental results confirm that microwave calcination at 600 °C for 5–7 min is effective for converting ZnS to ZnO without the formation of ZnO∙Fe2O3. Zinc extraction from the clinker reached 46.47% after treatment with microwave radiation at a power of 25 kW for the specified duration. Thus, this study opens up prospects for environmentally friendly zinc extraction from challenging-to-process resources.
