What is the role of flux in metallurgical processes?


To remove gangue, certain substances are mixed with it. These are called fluxes. A flux can be basic or acidic. Acidic flux removes basic impurity and basic flux removes acidic impurity.

Flux is also used for increasing conductivity.


SiO2 (Acidic flux)+CaO (Basic impurity) CaSiO3(Slag)


MgO(Basic flux) + SiO2 (Acidic impurity) MgSiO3 (Slag)
