The optimization of effective parameters in the leaching of sodium and potassium salts from electric arc furnace dust |
|
| چکیده انگلیسی مقاله |
This study optimized water-based leaching parameters for recovering Na and K salts from electric arc furnace (EAF) dust, while enhancing iron content in the residue. Characterization revealed the dust contained 14% Na₂O, 10.7% K₂O, and 45.3% Fe₂O₃, with particles <15 µm. Response Surface Methodology (RSM) identified temperature (60-70°C) as the most critical factor, achieving 83% Na and 68% K recovery at 25% solid content over 60 minutes. The process enriched the iron grade in the residue by 25% (from 32% to 40% Fe), as validated through large-scale experiments. The method offers dual environmental and economic benefits by minimizing waste and recovering valuable salts. |
