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 …
Slag is also called molten slag. The melt that floats on the surface of liquid substances such as metals during the pyrometallurgical process is composed mainly of oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), and often contains sulfides and a small amount of metal. Slag Introduction The composition of the slag is adjusted …
The objective of this review is to critically evaluate important aspects of aluminium dross generation, classification, properties, applications, and its commercial recycling techniques. A by-product of aluminium industry, aluminium dross is recycled by pyrometallurgy, hydrometallurgy, and hydrothermal processes, leading to aluminium recovery and generation …

Introduction. Slag examined in this study is defined as the predominantly silicate and oxide by-product derived from smelting metallic ore. The two main types of slag included in this discussion are from the primary production of ferrous ores, from iron and steel manufacturing, and from non-ferrous ores, from the recovery of base metals and some precious metals.
