Chromium-bearing slags produced during the stainless-steel smelting (SSS) are important recyclable secondary resources. Recovery of chromium from these slags is not only beneficial to increase the slag’s economic potential but also favorable to solve the environmental problems induced by the chromium (VI) in the slags. This study aims to review the technologies for recovering chromium from the chromium-containing SSS slags. To begin with, chromium resources and consumption around the world were analyzed. Then, the physicochemical characteristics of the SSS slags were provided, followed by a deep discussion on varieties of the normal and lately developed methods for recovering chromium from the slags, including physical separation, smelting reduction, thermal plasma, alkaline roasting-water leaching, alkaline leaching, and bioleaching processes. Specific attention was paid to the technical challenge appearing in the recovery of chromium from the SSS slags and to the possible measures for enhancing the chromium recovery by promoting the processing efficiency.

不锈钢冶炼（SSS）期间产生的含铬炉渣是重要的可循环再利用资源。从这些炉渣中回收铬，不仅有利于提高炉渣的经济潜力，而且有利于解决炉渣中铬（VI）引起的环境问题。这项研究旨在综述从含铬SSS炉渣中回收铬的技术。首先，分析了世界各地的铬资源和消费量。然后，提供了SSS渣的理化特性，然后深入讨论了从渣中回收铬的各种正常方法和最近开发的方法，包括物理分离，冶炼还原，热等离子体，碱性焙烧水浸出，碱性浸出和生物浸出过程。
