EAF dust: An overview on the influences of physical, chemical and ...
Apr 1, 2017 · Electric-arc furnace dust (EAFD) is one of the several process residues generated in mini mills during steel production. The presence of valuable zinc in EAF dust and the rising costs for waste disposal are the motivating factors for EAFD recycling or its incorporation into other materials.
A Look at the Process of EAF Dust Recycling - FEECO International …
As landfilling EAF dust becomes increasingly costly and we look for more sustainable methods for managing resources, the process of EAF dust recycling will continue to gain traction. This process provides a more sustainable and cost-effective alternative to current disposal methods.

Pyrometallurgical recycling of electric arc furnace dust
Apr 15, 2017 · The principle of pyrometallurgical processing of EAF dust is to extract valuable metals such zinc, iron, lead, etc, from the dust, essentially dependent on carbothermic reduction (e.g., Waelz kiln process), calcification (e.g., calcification process) or halogenation (e.g., chlorination process).
Recycling Steel Dust
The EAF dust generated by steel mills can be recycled in an economically viable way using the Waelz Kiln technology. The recycling process is part of the larger steel industry loop that allows the reuse of two important natural resources - zinc and iron.
Steel Manufacturing EAF Dust as a Potential Adsorbent for …
Electric arc furnace dust (EAFD) is a high-volume steel manufacturing byproduct with currently limited value-added applications. EAFD contains metal oxides that can react with H 2 S to form stable sulfides. Hence, the valorization potential of EAFD as an adsorbent material for syngas H 2 S removal was investigated.
Recycling EAF Steel Dust
The Steel Dust Recycling plant consists of a conditioning, blending and pelletizing facility for the EAF dust to be processed, a Waelz Kiln for processing the steel dust, storage and loading facilities for products to be sold, and the latest environmental control systems.
Electric arc furnace (EAF) dust: Application of air classification for ...
Feb 10, 2018 · Currently, more than half of the electric arc furnace (EAF) dust produced worldwide is still sent to landfill. This dust contains approximately 7.0% of the world Zn production. The other half of the EAF dust is processed pyrometallurgically or hydrometallurgically to recover …
