Abstract
Aluminum dross is a by-product generated during molten aluminum treatment and casting process. Knowing the composition of the dross will provide better environmental solutions through recycling and reusing. In this research, Rietveld XRD method is used to identify the crystalline phases present in dross. The XRD analyses were used to develop template files to ease the phase identification process. The Alpha Alumina phase is carried out by Rietveld XRD and separate XRD application since it is a crucial phase in aluminum smelting process. Omnian XRF standardless application was able to obtain the trace elements available in dross. Unifying sample preparation for XRD and XRF provided faster data reporting. In addition, Carbon content in dross is provided by a modified calibration of Leco Carbon analyzer. This methodology identified the crystalline phase of dross, the available trace elements, and the carbon content successfully with high accuracy and the fastest possible reporting time.
