use of slag scrap from manganese smelting in cement industry

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