What do you mean by acid slag and basic slag

What Do You Mean By Acid Slag And Basic Slag

Mar 09, 2020 Slag is the impurity that should be removed from raw ore to obtain pure metal. Acidic slag contains high concentrations of acidic or amphoteric oxides (SiO2, Al2O3). But the excess of basic oxide added makes the slag basic. If naturally such basic oxides are present as impurities, then also the slag is termed as basic.
