Zinc slag belongs to a solid waste from the zinc pyrometallurgical and hydrometallurgical industry. Containing a high content of zinc, lead and cobalt as secondary resource, zinc smelting slag is generated by the zinc pyrometallurgical process. And zinc leach residue, generated by the zinc hydrometallurgical process, usually contains zinc, germanium and indium. The large amount of zinc slag discharge causes environmental pollution and resource waste. Reducing the toxicity and increasing utilization of zinc slag are important measures to solve the negative impact of zinc slag on the environment. Here, we review the physical and chemical characteristics of zinc slag. The review focuses on the utilization of zinc slag: miscellaneous metal recovery and used for construction materials. Pyrometallurgical and hydrometallurgical methods for metal recovery are summarized. The utilization of zinc slag in construction materials is also discussed. Eventually, the related technological challenges and their possible solutions are described and discussed.
