A Review on Processing of Electric Arc Furnace Dust (EAFD) by Pyro-Metallurgical Processes

In recent years, the recovery of the valuable metals from iron-bearing solid waste from steel plant has been one of the most intensive research areas. Dumping of electric arc furnace dust is an environmental concern, and recovery of valuable metals like iron, zinc, lead from EAFD and safe disposal of residue has got enough attention. Evolution of improved and new processes has motivated industries to engage actively and targeting the new and efficient methods to recycle EAFD. The presence of valuable elements and increasing cost of waste incorporation are the motivational factors for the recycling of EAFD. In this article, the technologies that are in use to process EAFD have been discussed, and their advantages and disadvantages are also highlighted.
