Expert Answer
CaCO3 (limestone) acts as a basic flux.
Flux is the substance that chemically combines with gangue (earthy impurities) which may be present in the roasted or the calcinated ore to form easily fusible material called slag.
To remove impurities like silica (SiO2) and phosphorous pentoxide (P2O14) limestone is used.
