| Abstract Scope |
White dross is a hazardous waste generated during the primary production of aluminum (Al) and consists of a heterogeneous mixture of different oxides and metallic Al in the form of large flakes, lumps, particles, and dust. Due to the heterogeneity of the dross, sampling is challenging. A sampling tool with step-by-step procedures for its use has been published, with recommendations for how to pulverize and analyze different fractions of the dross using X-Ray Diffraction (XRD). In the present study, Electron Probe MicroAnalysis (EPMA) images of white dross samples were collected from the holding furnace in the Al casthouse during the production of Al alloy 5182 (AlMg4.5Mn0.4) and 6016 (AlSi1.2Mg0.4) have been quantified and cross-referenced to XRD analysis. The obtained results suggest that the image analysis method can quantitatively assess the influence of various process parameters on dross characteristics and contribute to optimizing industrial furnace operations aiming to reduce dross formation. |
