The function of neutral flux used in the pyrometallurgy of metal extraction is to increase the _____________ of the slag ?
Correct answer: A. Fluidity
- A. Fluidity
- B. Basicity
- C. Acidity
- D. Viscosity
Explanation
A neutral flux reacts with acidic or basic impurities and helps form a less viscous molten slag. Its practical purpose is therefore to increase slag fluidity, allowing impurities to separate more easily.
