The ores that are concentrated by floatation method are :
Correct answer: B. Sulphides
- A. Carbonates
- B. Sulphides
- C. Oxides
- D. Phosphates
Explanation
The correct answer is Option B: Sulphides. In the floatation process, the ore particles should have aerofillic in preference to gangue particles. Sulphide ores possess this characteristic, making them suitable for concentration by floatation method. Carbonates, oxides, and phosphates do not exhibit this property, which is why they are not concentrated using the floatation method.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
