Abstract

In the context of the circular economy, there is a need for advanced methods to recover metals from industrial waste, yet classical hydrometallurgical techniques are limited. Here, we review ultrasonic-assisted hydrometallurgical leaching with focus on the use of acids, bases, oxidants, bacteria and electrolysis. Oxidative leaching is done with ferric ions, dioxygen, ozone and hydrogen peroxide. Upscaling is also detailed. Ultrasonication allows to reduce the dosage of leaching agents, to reduce reaction time, and to enhance leaching efficiency. Large-scale equipments are still limited by low cavitation efficiency, low throughput, high usage costs, and high energy consumption.

通过超声波辅助湿法冶金浸出法从工业固体废物中回收金属：综述

在循环经济的背景下，需要采用先进的方法从工业废物中回收金属，但传统的湿法冶金技术却很有限。在此，我们回顾了超声波辅助湿法冶金浸出法，重点介绍了酸、碱、氧化剂、细菌和电解的使用。氧化沥滤使用了铁离子、二氧、臭氧和过氧化氢。此外，还详细介绍了放大法。超声波处理可以减少浸出剂的用量，缩短反应时间，提高浸出效率。大型设备仍然受到空化效率低、产量低、使用成本高和能耗高的限制。

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
