Abstract
The aluminum dross obtained from re-melting the scrap of the aluminum products through the secondary manufacture process was supplied from Alumisr company, Helwan, Egypt. The dross was analyzed chemically and mineralogically by means of X-ray diffraction analysis and was found to be strongly heterogeneous. It was classified into four classes varying according to the grain size distribution with an average of 50 to 0.06 mm. The content of aluminum metal is found to be between 86 and 16% in the different classes. It is composed mainly of aluminum nitride, aluminum oxide and spinel.
