Separation of Chlorides from EAF Dust
E-mail:
To utilize waste EAF dust for high-value applications, such as in construction materials and ceramics, the significant problem of the release of chlorides in the inorganic phase must be solved. An environmentally safe and economically efficient leaching proces sto extract chlorine elements is proposed in this paper. We found that the application of polar organic solvents can, in part, complement conventional wet methods. Among the test solvents (methanol, ethanol, and acetone), methanol was the most optimal for removing the chlorines when diluted with 10% (v/v) pure water.
