Slag Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of
