Zinc Production From EAF Dust at Cape Gate — A Case Study (Room 406)

The EZINEX® process to produce zinc from the direct treatment of EAFD was developed by Engitec Technologies in Italy. This process is a hydrometallurgical approach that produces high-quality zinc and other salable products from the EAFD without the generation of additional wastes. This paper will discuss a successful 500 kg/day EZINEX demo plant trial conducted by Cape Gate and Engitec Technologies. The goal of the campaign was to demonstrate the technical and economic feasibility of the process for a future industrial project. Can the EZINEX process reduce the cost of production for galvanizing operations and effectively recycle internal wastes?
