Abstract

Language:

More than 20 kg of dust and sludge per ton of produced metal are generated in basic oxygen furnaces used in steel metallurgy. This waste contains various non-ferrous metals, including zinc, with concentrations ranging from 1 to 6%. The primary objective of this study was to investigate the potential for treating these wastes through ammonia leaching to reduce zinc content to acceptable levels for ferrous metallurgy applications. A systematic approach was employed to analyze the leaching process, focusing on waste samples with a zinc concentration of 2.82%. Comprehensive experiments were conducted to determine the efficiency of zinc removal using ammonia leaching methods. The results indicated that ammonia leaching effectively reduced zinc levels, achieving a target concentration of around 1%, thus enabling the waste to be used as a viable iron-bearing material for recycling. Furthermore, the study highlights the environmental benefits associated with the recycling process, specifically in mitigating the leaching of harmful metal compounds into groundwater and soil. This research provides valuable insights into zinc recovery and supports sustainable practices within metallurgical industries.
