Slag: Ore, Metal, Oxide, Sulfide, Atom, Temperature Control, Ferrous, Aluminium, Iron

High Quality Content by WIKIPEDIA articles! Slag is a partially vitreous by-product of smelting ore to separating the metal fraction from the worthless fraction. It can be considered to be a mixture of metal oxides; however, slags can contain metal sulfides (see also matte) and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve other purposes, such as assisting in smelt temperature control and minimizing re-oxidation of the final liquid metal product before casting.
