Abstract
EF steel dust, an industrial waste, it is usually treated by Wealtz kiln etc. and then zinc, lead and other valuables will be separated and recovered and simultaneously large quantity of clinker will be formed from the furnace. Clinker consists mainly of iron but metallic form is low therefore hardly to use it as iron raw material. In this study, some practical tests for gravity and magnetic separation and concentration of metallic iron had been carried out in an industrial scale. Finally, it was confirmed that effective iron enrichment is possible and then recycling of iron to EF should be realized as a steel making raw material. Now industrial plant is under planning.
