Flux is used to remove :
Correct answer: D. Silica and undesirable metal oxide
- A. Silica
- B. Metal oxide
- C. All impurities from ores
- D. Silica and undesirable metal oxide
Explanation
Flux is commonly used to remove both silica and undesirable metal oxides from ores during metallurgical processes. Silica is often a major impurity in ores, and flux helps to form slag that contains the silica and metal oxides, which can then be separated from the desired metal. The incorrect options are based on misconceptions about the role of flux in removing impurities, such as silica and metal oxides, from ores.
