Define 'Slagging operation'.

Text Solution

Verified by Experts

It is the process of formation of slag (low fusible substance) by the reaction of flux with impurities of the ore, during metallurgy.For example in the metallurgy off iron,CaO(a basic flux) is used to convert the acidic impurties `SiO_2` to `CaSIO_3`(slag).
`CaO+SiO_2toCaSiO_3`
